Many people weren’t able to resist the fear of missing out on the massive gains the early adopters were experiencing as crypto prices rose quickly. When the inevitable correction came and crypto prices fell, those who bought towards the end of the bull run immediately saw the value of their holdings halved. Despair and anguish followed, but the enthusiasm of the crypto community hasn’t faltered.

We don’t mean to suggest that the pandemic hasn’t been involved, because we think it has, but not in the way that this chart criminal implies — not, in other words, because it’s some kind of safe haven that traders flock to when they are worried about Covid cases rising; the data don’t bear that idea out.

Investing in cryptocurrency can be as easy as a few taps on your phone, and with crypto all over the news and coming up in conversations with friends, it’s tempting to dive right in. However, depending on your financial situation and appetite for investing risk, crypto might not be an appropriate investment for you right now — or ever.
Virtual currencies. Like fiat currency, virtual currencies such as Bitcoin, Litecoin, and Ether are intended as a medium of exchange that enables two parties to transact business. But there are important differences: No physical coins or bills. Virtual currencies exist only in computer code. Except for visual representation of Bitcoin and altcoins in advertising and displays, and coin-like tokens that may be produced for marketing purposes, there are no actual coins or bills. Not legal tender. Virtual currencies are not legal tender and are not issued or backed by a government. However, many virtual currencies, which are called convertible virtual currencies, can be redeemed for fiat currency on a number of exchanges. No regulation. Virtual currencies are not regulated by any government agency or authority. However, regulation is being considered, especially where virtual currencies function as securities when they’re used to raise capital and when traded on exchanges.

All the signs, however, were there. Like previous bubbles, people were basing their belief in the cryptocurrency on their emotions, not any intrinsic value. Then there was the FOMO element, which only compounded things. Essentially, bitcoin became an international fever. Random companies were “pivoting to blockchain” for no apparent reason other than that it seemed like a way to create buzz. But when the bubble bursts, FOMO turns into fear of losing, which makes for an especially rapid plunge.
With all of these shortcomings facing most of the competition, Safemoon is definitely in trouble. The Safemoon team has to do a lot to make the play competitive. Otherwise, not many people will be interested in this Safemoon. This means low demand, and this is how the value of Safemoon’s coin will plummet.
In early November, FTM formed an inverse head and shoulder pattern, eventually breaking the neckline with a steep rise close to $3.2. However, it is now recovering from the steep drop it experienced overnight along with the market. On its way down, it broke through several local support levels.
One investor who wasn’t deterred was Barstool Sports Inc. founder Dave Portnoy. In May, he announced to his 2.6 million followers on Twitter that he’d bought $40,000 worth, despite saying that SafeMoon could be a Ponzi scheme, a scam in which early investors’ returns are paid with funds coming from later buyers that collapses when new deposits dry up or too many people try to cash out.
