Why are some people not preferring to use well known reputed old wallet instead? USDT has many old reputed wallet that can be used for it. There are two that I can recommend which are open source. They are Metamask and Unstoppable wallet. If you need a bitcoin wallet that also has the USDT, you can go for Unstoppable wallet. If I see that possible scam wallet mentioned anywhere, I can not go for it not to talk of making findings to know whether is a scam wallet or not.
