The only positive change over the last 24 hours on Coinmarketcap (top 100): Tether...
By that logic, all fiat and even precious metals had a green candle against crypto. Lol
Yeah, I'm about as anti-tether as anyone now, but that would be expected if USDT was doing it's job of tethering to the USD.
Bitcoin fell, so the USD(T) went up in comparison.
The real problems will start when that isn't the case, rather USDT falls with Bitcoin out of the 1 USD range, then it could come crashing down.
