The inability to get SEC approval really held back bitcoin and cryptocurrencies in general. It sent the message, says Innes, “that there wasn’t underlying support from Wall Street.” Meanwhile, the price dropped from around $10,000 to $6,000.
Initially, Binance.US considered listing up to 30 crypto assets, with those deemed most important making it to the Phase 1 list. Some have noted the absence of high-profile Binance IEOs (initial exchange offerings) from this list as well as the lack of support for Tron (13th by market capitalization at the moment).

Through instructions in their source codes, cryptocurrencies automatically adjust to the amount of mining power working to create new blockchain copies — copies become more difficult to create as mining power increases and easier to create as mining power decreases.
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.
