Also, the heavy reliance on stablecoins "BTC/USDT" in exchange is something scary and may prompt further price manipulation in the future.
I'm not a fan of stablecoins either, but despite the hate going towards them, especially USDT, they are doing their job exceptionally well. In fact, these tokens are one of the few tokens/coins with an actual utility.
USDT generates more volume than the tokens it has in circulation, and that on a daily basis. If that isn't a damn good utility in action, then I don't know what is. The fud wasn't enough to have its value tank further.
Bitfinex recently added a USDT/USD pair. I never expected them to list that pair, but they finally did it, and it will help them buy up sub $1 tokens and avoid paying $1 to people for coins they bought a few % lower.
