I want to buy some Tether USDT.
but the bitgo wallet don't have Tether wallet.
Which wallet is the best for USDT?
USDT is a ERC-20 token which means it is a token on the Ethereum Ecosystem. Since a few months aso there is also a USDT on the Binance Smart Chain, so every wallet that is supporting ERC-Tokens or Binance Smart chain Tokens can be used to deposit and withdraw USDT and pretty much every big wallet is supportin both Ethereum and Binance Smart chain, so you can freely choose between metamask, trustwallet or exodus just to give a few examples. You should consider though that USDT is not considered as the safest Stable coin out there, as there are others like for example USDC that seem to be more secure in therms of reserves.
