How do you turn that tether into money to your bank account? Is the process easy? You have to create a tether account right? Then send the money to your bank account? Is verification easy for this? Also what are the fees for this? For example say you have 5000 dollars in usdt. You want to cash it out to bank. When you cash it out, how much you get back to your bank after fees? Is it fixed percentage? And is it an ach or wire transfer? Is there a minimum/max?
Guys above you have said it all. However, with this question you are asking again, I feel you are complicating things for yourself. You do not have to send USDT to another exchange to convert to fiat. Once you want to make any withdrawal from bittrex, just send the USD equivalent of the BTC you want to withdraw to exchanges like coinbase and the likes, and you can convert your BTC to your normal currency which would be sent to your bank account from there. However, there are some things I guess you should know first;
1. Unless you plan on trading, you really do not need bittrex
2. Your BTC is all you need in most exchanges to convert to fiat which would be sent to your bank account.
3. You have to find the exchanges you can make use of in your area as some may not be applicable for you to use in your country. If you are in the US though, you can make use of coinbase. If you are in a different country, you can check the supported countries here
