bittrex is in the USA, we know that USA is very opposed to the existence of crypto, it is possible that bittrex was not allowed to make its own coins in the USA. so that until now they have not made it
It is incorrect. the USA government just want to implement strict rules, and managements, laws on crypto. They will not be able to restrict or wipe out crypto currencies. Because blockchain and crypto currencies are future of human civilization, and the USA are unable to damage that revolution. They should make law managements, and also adapt themselves to changes in crypto.
