Here's how I got my coins back/free,
For me it was the NXT coins, but actually the name of the coin is not important.
Because Bittrex has started a new website for people outside the USA (international.bittrex.com), they have convinced everyone that ID, Passport or other legitimacy WITH social security number, tax number etc. was mandatory is NOT true.
If you want to continue with Bittrex you will not get away with it, but, if (like me) you cannot live with these new rules then they are obliged to release your coins, provided that the following applies to you:
If you were already basic verified on their old site then they CANNOT oblige you to enforce their ID Verification

It's actually simple, you had a contract with Bittrex, Bittrex changed the rules and so you also have the right to refuse and switch to another exchange at that time.
Bittrex will do everything to force you to take these steps anyway, because yes you cannot trade with your coins in the meantime (that is called blackmail).
But with me they were at the wrong address, I spammed their Mail Twitter accounts completely full of pictures with scammers, thieves, etc.
or
They also tried to block my account at Twitter, but from a short email it was clear that I was not doing anything that was not true.
I also told them through tickets that it would only get worse and I would not stop until I got my coins back (I lost about 4000 euros due to Bittrex)
I know that you have to do a verification at most exchanges, BUT I decide where I do that and not Bittrex.
If a group of people start to join forces to go to court, I think that will also participate.
Bittrex says that they are in Europe and must comply with European rules, but they are in Liechtenstein and they have nothing to do with the European Union, which is why there are also many companies go there that want to evade taxes.
This is my story, 4000 gone, but that was my choice and mine alone.
