The two problems as I see them are:
- Is USDT actually backed 1:1 by USD / cash equivalents as Tether claims? w/o independent audits we have no idea. So technically, if you hold USDT on an exchange and use it to trade alts and evade the taxman, then if this whole thing falls apart your USDT might be worthless.
- The owners of Bitfinex and the people who run tether are the same set of people. So theoretically it's possible that
+ Bitfinex generates artificial demand for USDT somehow
+ Finds a way to swap actual USD for USDT (customer
deposits? 19bn worth of customer deposits? Unlikely)
+ In turn goes around and buys BTC with that USD for some
reason
+ Does it w/ enough vol that all the arbitrage bots won't
be able to arbitrage it away.
These are a lot of ifs and I'm just not seeing the incentives here as best case Finex gets stuck with a bunch of BTC they inflated themselves which isn't in their interest.I'm not a finance guru, so I'd love it if someone more informed than me can comment on how someone can pull this off.
