I've managed to transfer so many coins of mine from one exchange to the other. Just both the coins need to be listed and the minimum deposit amount should be noted (some have a minimum of 10 tokens).
Until both the exchanges are listed the coin and are trading with same symbol and coin then you can do it directly from yobit to bittrex. But first check the both exchange wallet are in working condition or in maintenance because in yobit their are lot of coins which they have stopped in the name of wallet maintenance but the same coin wallet will be working good in other exchanges. So be careful to do this type of transactions
With bittrex, it's fine but yobit has most of the wallets under maintenance. Also, avoid yobit as much as possible as they take weeks to reply if coins don't get deposited in the wallet.
