The decision by Tesla, and announced by Musk, was seen by some as a slight on the credibility of cryptos to become a viable method of payment against physical currencies.
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.

The spread is the difference between the buy and sell prices quoted for a cryptocurrency. Like many financial markets, when you open a position on a cryptocurrency market, you’ll be presented with two prices. If you want to open a long position, you trade at the buy price, which is slightly above the market price. If you want to open a short position, you trade at the sell price – slightly below the market price.
Margin is usually expressed as a percentage of the full position. A trade on bitcoin (BTC), for instance, might require 15% of the total value of the position to be paid for it to be opened. So instead of depositing $5000, you’d only need to deposit $750.
