Bittrex the US based cryptocurrency trading platform has disable Bitcoin Wallet.
Bittrex earlier today announced on their SUPPORT PAGE that they will close deposits and withdrawals of Bitcoin due to BIP 91 activation.
Bitcoin wallet will still be closed till most of the hash power chain is clearly established.
As of writing this article, Bittrex has already disable their Bitcoin wallet although "trading will remain active" according to Bittrex.
Other Trading platforms are expected to follow same trend.
