I'm trying to move my ETH from blockchain wallet to Bittrex address, but as soon as I paste bittrex address i got this message "Contract addresses are not supported -- At the moment we only support ETH. You cannot receive REP, ICN.." Have no clue what contract address is ?
Honestly, my only experience on this kind of situation is when I tried to transfer altcoin from my MEW to bittrex but never experience to transfer using blockchain going to Bittrex. And everything I do transactions I started to send from small amount first to test if they will transfer it to the platform then once its successful that's the time I need to send it all over that exchange site platform.
