So will there be two coins immediately on 12:20 UTC time on August 1. or is there some sort of lock in period or something of that sort ?
Also how exactly do I use the Bitcoin ABC client to split the coins? I send a transaction with some flag and then another without the flag?
way easier to send your bitcoin to a paper wallet now. after the fork send it back to your regular bitcoin wallet. then all you're left with is bcash private keys.
no security worries and no hassles.
