Different types Erectile Dysfunction

The following are some of the possible causes of erectile dysfunction:

 

1. Drug-induced ED.

A great variety of prescription drugs, such as blood pressure medications, anti-anxiety and antidepressant medications, glaucoma eye drops, and cancer chemotherapy agents are just some of the many medications associated with ED. Many experts believe that atrophy, a partial or complete wasting away of tissue, and fibrosis, the growth of excess tissue, of the smooth muscle tissue in the body of the penis (cavernous smooth muscle) triggers problems with being able to maintain a firm erection. Poor ability to maintain an erection is often an early symptom of erectile dysfunction. Although the condition is called venous leak, the real problem is not with the veins but malfunction of the smooth muscle that surrounds the veins. The end result is difficulty with maintain a firm erection (losing an erection too quickly) that is now believe to be an early manifestation of atherosclerosis and vascular disease.

2. Organic Erectile Dysfunction

Organic ED involves abnormalities the penile arteries, veins, or both and is the most common cause of ED, especially in older men. When the problem is arterial, it is usually caused by arteriosclerosis, or hardening of the arteries, although trauma to the arteries may be the cause. The controllable risk factors for arteriosclerosis--being overweight, lack of exercise, high cholesterol, high blood pressure, and cigarette smoking--can cause erectile failure often before progressing to affect the heart.

3. Neurologic causes.

There are many neurological (nerve problems) causes of ED. Diabetes, chronic alcoholism, multiple sclerosis, heavy metal poisoning, spinal cord and nerve injuries, and nerve damage from pelvic operations can cause erectile dysfunction.

4. Hormone-induced ED.

Hormonal abnormalities, such as increased prolactin (a hormone produced by the anterior pituitary gland), steroid abuse by bodybuilders, too much or too little thyroid hormone, and hormones administered for prostate cancer may cause ED. Low testosterone can contribute to ED but is rarely the sole factor responsible for ED.

5. Diabetes.

Erectile Dysfunction is common in people with diabetes. An estimated 10.9 million adult men in the U.S. have diabetes, and 35 to 50 percent of these men are impotent. The process involves premature and unusually severe hardening of the arteries. Peripheral nephropathy, with involvement of the nerves controlling erections, is commonly seen in people with diabetes.

6. Depression.

Depression is another cause of ED and is closely related to erectile dysfunction. Because there is a triad relationship between depression, ED and cardiovascular disease, men with depression should be fully evaluated for medical illness as well as psychological factors. Some antidepressant medications cause erectile failure.

Are Cryptocurrencies Safe Investments?

 Are Cryptocurrencies Safe Investments?

Cryptocurrencies have attracted a reputation as unstable investments, due to high investor losses as a result of scams, hacks, and bugs. Although the underlying cryptography is generally secure, the technical complexity of using and storing crypto assets can be a major hazard to new users.

In addition to the market risks associated with speculative assets, cryptocurrency investors should be aware of the following risks:

User risk: Unlike traditional finance, there is no way to reverse or cancel a cryptocurrency transaction after it has already been sent. By some estimates, about a fifth of all bitcoins are now inaccessible due to lost passwords or incorrect sending addresses.

Regulatory risks: The regulatory status of some cryptocurrencies is still unclear, with many governments seeking to regulate them as securities, currencies, or both. A sudden regulatory crackdown could make it difficult to sell cryptocurrencies, or cause a market-wide price drop.

Counterparty risks: Many investors and merchants rely on exchanges or other custodians to store their cryptocurrency. Theft or loss by one of these third parties could result in the loss of one's entire investment.

Management risks: Due to the lack of coherent regulations, there are few protections against deceptive or unethical management practices. Many investors have lost large sums to management teams that failed to deliver a product.

Programming risks: Many investment and lending platforms use automated smart contracts to control the movement of user deposits. An investor using one of these platforms assumes the risk that a bug or exploit in these programs could cause them to lose their investment.

Market Manipulation: Market manipulation remains a substantial problem in the cryptocurrency space, and some exchanges have been accused of manipulating prices or trading against their customers.

Despite these risks, cryptocurrencies have seen a major leap in prices, with the total market capitalization rising to over $1 trillion.

 Despite the speculative nature of the asset, some have been able to create substantial fortunes by taking on the risk of investing in early-stage cryptocurrencies.

Advantages and Disadvantages of Cryptocurrency

Cryptocurrencies were introduced with the intent to revolutionize financial infrastructure. As with every revolution, however, there are tradeoffs involved. At the current stage of development for cryptocurrencies, there are many differences between the theoretical ideal of a decentralized system with cryptocurrencies and its practical implementation.

Some advantages and disadvantages of cryptocurrencies are as follows.

Advantages

Cryptocurrencies represent a new, decentralized paradigm for money. In this system, centralized intermediaries, such as banks and monetary institutions, are not necessary to enforce trust and police transactions between two parties. Thus, a system with cryptocurrencies eliminates the possibility of a single point of failure, such as a large bank, setting off a cascade of crises around the world, such as the one that was triggered in 2008 by the failure of institutions in the United States.

Cryptocurrencies promise to make it easier to transfer funds directly between two parties, without the need for a trusted third party like a bank or a credit card company. Such decentralized transfers are secured by the use of public keys and private keys and different forms of incentive systems, such as proof of work or proof of stake.

Because they do not use third-party intermediaries, cryptocurrency transfers between two transacting parties are faster as compared to standard money transfers. Flash loans in decentralized finance are a good example of such decentralized transfers. These loans, which are processed without backing collateral, can be executed within seconds and are used in trading.

Cryptocurrency investments can generate profits. Cryptocurrency markets have skyrocketed in value over the past decade, at one point reaching almost $2 trillion. As of May 2022, Bitcoin was valued at more than $550 billion in crypto markets.

The remittance economy is testing one of cryptocurrency's most prominent use cases. Currently, cryptocurrencies such as Bitcoin serve as intermediate currencies to streamline money transfers across borders. Thus, a fiat currency is converted to Bitcoin (or another cryptocurrency), transferred across borders, and, subsequently, converted to the destination fiat currency. This method streamlines the money transfer process and makes it cheaper.

Disadvantages

Though they claim to be an anonymous form of transaction, cryptocurrencies are actually pseudonymous. They leave a digital trail that agencies such as the Federal Bureau of Investigation (FBI) can decipher. This opens up possibilities of governments or federal authorities tracking the financial transactions of ordinary citizens.

Cryptocurrencies have become a popular tool with criminals for nefarious activities such as money laundering and illicit purchases. The case of Dread Pirate Roberts, who ran a marketplace to sell drugs on the dark web, is already well known. Cryptocurrencies have also become a favorite of hackers who use them for ransomware activities.

In theory, cryptocurrencies are meant to be decentralized, their wealth distributed between many parties on a blockchain. In reality, ownership is highly concentrated. For example, an MIT study found that just 11,000 investors held roughly 45% of Bitcoin's surging value.

One of the conceits of cryptocurrencies is that anyone can mine them using a computer with an Internet connection. However, mining popular cryptocurrencies requires considerable energy, sometimes as much energy as entire countries consume. The expensive energy costs coupled with the unpredictability of mining have concentrated mining among large firms whose revenues running into the billions of dollars. According to an MIT study, 10% of miners account for 90% of its mining capacity.

Though cryptocurrency blockchains are highly secure, other crypto repositories, such as exchanges and wallets, can be hacked. Many cryptocurrency exchanges and wallets have been hacked over the years, sometimes resulting in millions of dollars worth of "coins" stolen.

Cryptocurrencies traded in public markets suffer from price volatility. Bitcoin has experienced rapid surges and crashes in its value, climbing to as high as $17,738 in December 2017 before dropping to $7,575 in the following months.

 Some economists thus consider cryptocurrencies to be a short-lived fad or speculative bubble.

Blockchain

 

Blockchain

Central to the appeal and functionality of Bitcoin and other cryptocurrencies is blockchain technology. As its name indicates, blockchain is essentially a set of connected blocks or an online ledger. Each block contains a set of transactions that have been independently verified by each member of the network.

Every new block generated must be verified by each node before being confirmed, making it almost impossible to forge transaction histories.1 The contents of the online ledger must be agreed upon by the entire network of an individual node, or computer maintaining a copy of the ledger.

Experts say that blockchain technology can serve multiple industries, such as supply chains, and processes such as online voting and crowdfunding. Financial institutions such as JPMorgan Chase & Co. (JPM) are testing the use of blockchain technology to lower transaction costs by streamlining payment processing.2

Cryptocurrency investment scams

 

Scammers are always looking for new ways to steal your money, and the massive growth of cryptocurrency in recent years has created plenty of opportunities for fraud. Cryptocurrency crime had a record-breaking year in 2021 – according to a report by blockchain data firm Chainalysis, fraudsters stole $14 billion of crypto that year. If you’re interested in crypto, it’s important to be aware of the risks. Read on to find out more about common crypto scams, how to spot them, and how to avoid them.

Cryptocurrency investment scams

There are many types of crypto scams. Some of the most common include:

Fake websites

Scammers sometimes create fake cryptocurrency trading platforms or fake versions of official crypto wallets to trick unsuspecting victims. These fake websites usually have similar but slightly different domain names from the sites they attempt to mimic. They look very similar to legitimate sites, making it difficult to tell the difference. Fake crypto sites often operate in one of two ways:

• As phishing pages: All the details you enter, such as your crypto wallet's password and recovery phrase and other financial information, end up in the scammers' hands.
• As straightforward theft: Initially, the site may allow you to withdraw a small amount of money. As your investments seem to perform well, you might invest more money in the site. However, when you subsequently want to withdraw your money, the site either shuts down or declines the request.

Phishing scams

Crypto phishing scams often target information relating to online wallets. Scammers target crypto wallet private keys, which are required to access funds within the wallet. Their method of working is similar to other phishing attempts and related to the fake websites described above. They send an email to lure recipients to a specially created website asking them to enter private key information. Once the hackers have acquired this information, they steal the cryptocurrency in those wallets.

Pump and dump schemes

This involves a particular coin or token being hyped by fraudsters through an email blast or social media such as Twitter, Facebook, or Telegram. Not wanting to miss out, traders rush to buy the coins, driving up the price. Having succeeded in inflating the price, the scammers then sell their holdings – which causes a crash as the asset's value sharply declines. This can happen within minutes.

Fake apps

Another common way scammers trick cryptocurrency investors is through fake apps available for download through Google Play and the Apple App Store. Although these fake apps are quickly found and removed, that doesn't mean the apps aren't impacting many bottom lines. Thousands of people have downloaded fake cryptocurrency apps. 

Fake celebrity endorsements

Crypto scammers sometimes pose as or claim endorsements from celebrities, businesspeople, or influencers to capture the attention of potential targets. Sometimes, this involves selling phantom cryptocurrencies that don't exist to novice investors. These scams can be sophisticated, involving glossy websites and brochures that appear to show celebrity endorsements from household names such as Elon Musk.

Giveaway scams

This is where scammers promise to match or multiply the cryptocurrency sent to them in what is known as a giveaway scam. Clever messaging from what often looks like a valid social media account can create a sense of legitimacy and spark a sense of urgency. This supposed ‘once-in-a-lifetime’ opportunity can lead people to transfer funds quickly in the hope of an instant return.

Blackmail and extortion scams

Another method scammers use is blackmail. They send emails that claim to have a record of adult websites visited by the user and threaten to expose them unless they share private keys or send cryptocurrency to the scammer.

Cloud mining scams

Cloud mining refers to companies that allow you to rent mining hardware they operate in exchange for a fixed fee and a share of the revenue you will supposedly make. In theory, this allows people to mine remotely without buying expensive mining hardware. However, many cloud mining companies are scams or, at best, ineffective – in that you end up losing money or earning less than was implied.

Fraudulent initial coin offerings (ICOs)

An initial coin offering or ICO is a way for start-up crypto companies to raise money from future users. Typically, customers are promised a discount on the new crypto coins in exchange for sending active cryptocurrencies like bitcoin or another popular cryptocurrency. Several ICOs have turned out to be fraudulent, with criminals going to elaborate lengths to deceive investors, such as renting fake offices and creating high-end marketing materials.

How to spot cryptocurrency scams

So, how to spot a crypto scam? Warning signs to look out for include:

Promises of guaranteed returns: No financial investment can guarantee future returns because investments can go down as well as up. Any crypto offering that promises you will definitely make money is a red flag.

A poor or non-existent whitepaper: Every cryptocurrency should have a whitepaper since this is one of the most critical aspects of an initial coin offering. The whitepaper should explain how the cryptocurrency has been designed and how it will work. If the whitepaper doesn’t make sense – or worse, doesn’t exist – then tread carefully.

Excessive marketing: All businesses promote themselves. But one way that crypto fraudsters attract people is by investing in heavy marketing – online advertising, paid influencers, offline promotion, and so on. This is designed to reach as many people as possible in the shortest time possible – to raise money fast. If you feel that the marketing for a crypto offering seems heavy-handed or makes extravagant claims without backing them up, pause and do further research.

Unnamed team members: With most investment businesses, it should be possible to find out who the key people behind it are. Usually, this means easy-to-find biographies of the people who run the investment plus an active presence on social media. If you can’t find out who is running a cryptocurrency, be cautious.

Free money: Whether in cash or cryptocurrency, any investment opportunity promising free money is likely to be fake.
