As expected. Once defi project starting to move on tron protocol (TRC-20). This kind of scam activities will likely showing up. Not included, lots of useless project (or copy paste project) will be built on there.
Scammers are constantly adapting to the situation, as TRX transactions are peanuts compared to ETH. Not a surprise though as all the these scam attempts are very basic and doesn't take much time,money and effort to set them up. They mostly count on the investors being bad at math so for many of them 4-5% daily profit seems reasonable, while even 1% daily is way too far much and not sustainable.
