A plain reply to "What is a usdt wallet?" starts with what a wallet actually holds. A bitcoin wallet is an app or a small device that keeps the private keys for coins recorded on the bitcoin network; the coins never sit in the wallet itself. For someone about to pay a casino in crypto, the wallet is the first tool to set up. A few decisions taken in its first ten minutes shape everything after: who keeps the keys, which networks it handles, and which device it lives on.
How to choose a bitcoin wallet depends on its intended use, not on a ranking. A few tests help. The keys stay with the user, or it is clear who holds them. The backup words follow a common standard that other compatible wallets can restore. The sender can set the network fee, which matters more than any promise of a bitcoin wallet with low fees, since that fee goes to the network rather than the wallet. Open source code or a long public record counts for more than lists of the best wallets, many of which are paid placements.
A USDT wallet is any wallet that supports USDT on the network being used, because USDT runs on several networks, among them TRC20 on TRON, ERC20 on Ethereum and BEP20 on BNB Smart Chain. A balance on one network does not move to another by itself. To create a USDT wallet, set up the app as usual, back up the words, then add USDT and choose the network before copying the address. Fees are paid in that network's coin: TRX on TRON, through energy and bandwidth or TRX burnt for them, ETH gas on Ethereum, BNB on the BNB chain.
By clear tests rather than rankings: who holds the keys, a backup that compatible wallets can restore, a fee the sender can set, and a long public record.

Only from its listing in an app store or the developer's own site, checked by developer name, since fake copies imitate known names and icons.
The right network chosen before copying the address, plus some of that network's coin for fees: TRX on TRON, ETH on Ethereum, BNB on BNB Smart Chain.
No. An account is a login at an exchange that holds the keys for its users; a personal wallet needs no account and no identity checks.
