The biggest scam, which will cause a shock to crypto markets (for better or worse, capital flight will fly to other stablecoins and or back to Bitcoin) is Tether, USDT.
Yep, USDT will destroy the market if it gets shut down.
Tether is another one that a lot of people have been talking about. It’s quite strange how these scammers keep mingling themselves among the originals. And it’s quite sad that a lot of people are not aware of how bad these coins are, and I wouldn’t even blame those people who mention them, it’s not all of them that are bots or paid guerrilla marketing teams, some people usually think that any coin that is on the top positions like the top tens or twenty are a good options, so they are rushing into these scams without knowing it at all. That’s very bad. The one of Tether is the one I know very will that will hit the cryptocurrency market badly.
