Exchange tokens are not that reliable and its hard to know the one that will survive, with the SEC hunting down any exchange they feel like I think they are more risky, it's better to go for decentralized exchange tokens like GMX, I think with what happened to Binance it's time that DEX will be more attractive to users than Centralized exchanges, anything can happen to any exchange at any time, even the biggest ones, Huobi could be the next target too who knows? Invest only what you can afford to lose.
