Going from USDT to USD in a roundabout way through BTC doesn't change anything if USDT themselves are bullshit.
RE your EDIT: it is, but deep downthread like this, it's always luck what you get. Also don't worry about the downvotes, everyone gets their share of them here :).
I dont know the answer to the above, but its critical for the future price of bitcoin and is really really important. Everyone just seems to assume they held the bitcoin, which is a crazy move. If they could have sold for USD, it makes sense to me they would have...thats why I think its an important question. It doesnt seem to interest anyone else tho, which is fine.
The comment above said liquidity dictates they could not have, that they must still be holding bitcoin. But I also say today, bitfinex'ed, the blogger that has been on this story, says they redeemed 330 million in past 24 hrs. Which is far above the 10% of 2 billion number he said of the entire crypto market is backed by USD. So to say the liquidity doesnt exist doesnt seem to make sense, there seem to be a lot of dollars into crypto. 1 million people with $1000 invested is a billion alone. That isnt crazy.
