@exstasie. The American government pulling the rug on Tether is different from Tether only losing its banking partner.
Sure but the result is the same: people panic buying out of USDT and if possible Bitfinex USD, and into crypto, due to fear of underlying insolvency or imminent collapse.
Also, your argument implies that it was a pump and dump.
How so? If people dump USDT because they are scared it might become worthless, how does that make it a pump and dump?
Taking down Tether and iFinex will remove billions of USDT from the market and the reduced liquidity might not handle the panic.
It's impossible to know what would happen. It partly depends how it goes down. If it's like with Bitmex (domains and servers not seized) then maybe Bitfinex and Tether's remaining assets could be unwound relatively smoothly.
What I do know is that USDT and Bitfinex markets are tightly pegged to other spot exchanges through arbitrage. Traditionally when this peg is broken due to banking or liquidity problems or FUD, Tether and Bitfinex work quickly to sort out liquidity for their very largest corporate clients, who can then arbitrage the markets back into line. Like I said, a lot may depend on whether we're talking about a full blown seizure like BTC-e in 2017, just the unsealing of indictments like with Bitmex this year, or somewhere in between.
Exchange hacks and failures also haven't been affecting the market all that much in recent years. I wouldn't necessarily expect a crash like after the Mt. Gox collapse. But Bitfinex and Tether are quite large so like I said, it's hard to know what would happen exactly.
All I know is you better have your popcorn ready.
