Don't withdraw big amount from Bittrex now. They are on the wrong fork, do only small amount. I undertand if you have 600k, it would be a pain to make tons of 100 NJA withdraw.
For the moment, don't withdraw big amount from Bittrex
Maybe if we talk to them they will end to switch on the good fork. The bad fork is still useless, it's a non sense to keep it.
We have see with coinader that it's possible, bittrex can do it too !
so I bougth 100k coin, sent just 1 and it was good, then I sent half of them 53k, and they never arrived in my wallet, I still have 53k on bittrex.
For what I've understood, for the 53k that I sent in my wallet I cant do anything, they are lost! right?
