I'm surprised how easily people send their IDs to unknown persons (let it be bittrex or somebody else). They can simply use your documents to open a bank account and doing some illegal business all in your name....
I also have couple of thousands usd there, but not considering sending them anything.
It would appear Bittrex has changed their TOS again without notification... The restricted states where NOT on there when I signed up!
