Stocks will be temporary disabling their BBR market from their available pairings until such time that they launch their new exchange and are able to dedicate resources to fix their integration. Other pairings there also have integration issues and have been taken offline for maintenance.

If you are planning on withdrawing from Stocks DO NOT use their payment ID function for withdrawals otherwise you will lose your funds. Withdraw to a local wallet then if you plan on trading send to BTC-Alpha.

Myself, crypjunkie and others have fully tested BTC-Alpha and there are no issues whatsoever with their platform. As long as you don't send directly from stocks.exchange to BTC-Alpha you will be OK.

Please notify all miners and pool operators so they can plan accordingly.
