I recently watched some traditional cable and was shocked by the number of crypto ads bombarding viewers. I have to imagine that this market was goosed up by retail investors trading on coinbase and binance just as the e-betting market was. The only difference between crypto and e-betting is that everyone got to be a winner on the crypto markets for a while. As users lose out, and exchanges stop ad campaigns - how long will that last?
Crypto needed a tangible market/reason d'etre to be valuable. This required lower transaction fees, cheap audits, and a reasonable degree of price stability. We haven't seen any of that materialize except for cheap auditing. Cheap auditing isn't much use if there isn't anything of interest to audit.
I'd doubt BTC will go to zero, but I wouldn't be surprised if the entire covid rally gets wiped out and we see BTC 6k again.
