Where can I buy bitcash Is there any where I can buy bitcash ahead of the fork? Or do I need to keep my bitcoin in wallets that won't signal SegWit?
Bitcoin Cash is technically just Bitcoin before the fork, it doesn't really exist as such, and any Bitcoin you own will become Bitcoin Cash as well after the fork (because your UTXOs will be valid in the shared chain before the fork and thus valid in both branches). Until the fork happens, there is only one blockchain, hence the term fork.
