Anyway, if people start to panic and lose trust in tether, wouldn't that mean higher bitcoin/altcoin prices? Surely they'll either be buying crypto to get rid of them or trade them for actual cash possibly bellow $1?
Where would you do that? Tether has already stated publicly they will not honor tether tokens if they don't want to. that is the funniest thing I ever read and yet people still buy them. Shit, I posted that in this thread months ago with the quote when it got added to their website.
Thanks.

How did exchanges got tether? Lets say poloniex, they paid USD to get them or they just print them themselves?
My guess is that btc and kraken essentially
are the Omni foundation. They pooled some USD, EUR, JPY and issued corresponding tether. But they reserve the right to disregard your redemption request. AFAICT, the only way to redeem it for USD at retail is to sell for USD on kraken, or buy crypto with it, and sell that wherever you like. As far as bfx is concerned, there is simply no difference between USDT and USD. It is entirely fungible. On kraken, where the exchange is explicit, there is often a small delta to NAV, but rarely enough to make a retail arbitrage, and never for long.
I didn't even know there was a USD/USDT pair, thx. Kraken is worthless to US Residents though afa I'm concerned.
