I must however say that Bittrex, among many other exchanges, are having problems way too often.
I posted a thread about this
here.
A couple of weeks ago i opened an account with poloniex for i want to start trading but i have read that they are having some problem. So i did not continue to transfer funds to them.
Then i research and find bittrex as the next option, so a few days ago i opened an account with bittrex and got verified as well. I just need to transfer fund to start trading. Now bittrex is encountering problem and disabling account and suspending withdrawal.
My question is, what is the next best exchange to do my trading?
It depends on where you are located. I personally use Kraken, which even though it has had and has lots of problems with its trading engine, has not had general deposit or withdrawal problems so far.
You must however be careful when setting up 2FA on Kraken. It's not as straightforward as it might seem and you might end up with your account being able to be unlocked without any 2FA code.
