I've mailed to bittrex and it response me with this...
"Yes... but none of the exchanges have switched.. poloniex is on the old wallet as well. Need to see if the community takeover is actually working because the old chain is still working fine"
WTF is with the bittrex? You mean to say that they will still show that f**king message "Wallet offline, upgrade pending." and no news about why the heck are they doing this? Just a stupid reason...
