A run on Tether would create absolute, utter panic across the crypto space. The first immediate problem would be that most, if not all major exchanges would become paralyzed as they'd be forced to suspend withdrawals and trading of certain coins (or trading entirely). Prices would go crazy as exchange IT systems and trading engines seized up and failed under the load; verification of transactions on the chains could be hours behind the exchanges. The market would splinter as some venues freeze up, some go dark, and desperate traders flood the remaining live ones to cash out whatever they can by any possible means. Liquidity (at least on the bid side, lol) would vanish entirely as pro crypto trading firms and MMs are suddenly confronted with a shattered market unable to process trades, and where winning derivatives bets won't be paid out because the counterparties are bankrupt - exactly like 2008 but sans government intervention. BTC spreads would explode out to several thousand dollars, and the volatility would be insane, with a single-day $20k range easily in the cards.
Most secondary coins would fall by 90%+ in one day, or in effect cease trading. On those venues where a more or less continuous market did remain functioning, my guess is we'd see BTC initially stabilize around $10k. However, this wouldn't be the end of the bear market; with the crypto ecosystem in ruins and the narrative busted, the HODLers would start limping home and the space would be staring down years of brutal bankruptcy proceedings and lawsuits. Ongoing BK cases would result in periodic mass coin dumps into whatever market remained, crushing the price over and over. Many leading figures in the crypto space will be facing criminal indictments in more than one country. Institutional and investor revulsion would put an end to talk of "institutional adoption", or an American crypto ETF. In the next 2-3 years, Bitcoin would definitely fall below the 2018 levels of ~$3k and I wouldn't be surprised to see it back below $1k.
That's if Tether fails. If not, the bear market will be nasty but not so cataclysmic as described here.
Interesting, thanks.
