What freaks me out a bit about Tether is the fact that they still linked to a bank account that can be frozen or blocked at any given time. I do not trust banks and the government behind those banks. I
can see why they doing this, but I do not trust the bank connection behind this technology. I know the exchanges have the same problem, but some of them are regulated and insured against losses, or
that is what we hope.... How is Tether any different? At some stage, you have to go back to fiat in any way... right?
They probably don't ever have 'to go back to fiat'. Basically, on the first day a rich guy just made on big ass deposit. I think that Brock dude was involved. Then, those initial USDT were traded for BTC slowly. Now, they just go back and forth between USDT and BTC all day long. There aren't really any more transactions In/Out of USDT/Fiat. If needed, they can take another USD deposit - or reverse. But, that is not part of the daily action. The daily action is all USDT < - > BTC. So, the fiat just pretty much sits there doing nothing.
Getting the whole thing up to have some liquidity is the hard part. But just today it traded $500,000 so there are enough buyers and sellers now. No more need to create/destroy more of the coin. If there is a huge buy run that causes the price to go whacky, they'll put more into circulation with some more cash deposits. But that isn't a daily event.
