Are there coins that are notoriously tricky to trade for other reasons perhaps?
In my opinion trading Altcoin - USDT is very complicated
Example of ETH - USDT, sometimes the bitcoin price goes up a lot and the price of ETH - USDT goes down a lot, because ETH also fell in the ETH - BTC pair; and sometimes the price of bitcoin falls a lot and also the ETH - BTC pair falls a lot resulting in a big price drop in the ETH - USDT pair.
In the case of BNB - USDT Is a big headache, it outperforms the other altcoins.
This is my opinion, I prefer only the pair BTC - USDT.
