USDT tether market cap almost made 20x in 2 years. Regardless the never-ending controversy around it and affiliated crypto exchange Bitfinex it still dominates majority of CEX'es. Maybe it's just my perception, but usually for exotic tokens you can find pairs only with USDT. But just in case, let's say the disaster happens, what percentage of you stable coins is in USDT? Few weeks back, I was trying to be in USDC, but it doesn't have many pairs.
