I have a question that
Lets assume that I have USDT 12000 ON my Binance US Account. If i withdraw USDT to my bank account in USA. What about the possibility and taxation about it?
Know that the US likes to lead in everything and they are the most advanced in Crypto regulation as of today, so be sure that you are legit and straightforward with provable transactions in the first place. Having satisfied that, the source of the money matters, so long as the money is an income, it is taxable even if it is less than a dollar.
Taxable Crypto earnings in the US include but are not limited to all the payments received (incentives, mining, hard fork, sweepstakes and any online activities that generate money as crypto) and gains from holding etc.
As a liable taxpayer in the US, you will be sure to report all the necessary tax returns, and if you are dealing with the exchanges in the US for the transactions, they would report it to IRS (Internal Revenue Service), and you will also be furnished with a copy of the report in case you need it for documentation.
