Who’ll be right on the money? A widely anticipated “hard fork” has split Bitcoin in two. Alternative cryptocurrency Bitcoin Cash will allow for more transactions at any moment, as opposed to the seven-per-second limit built into the original system. Some users of Bitcoin, collectively valued at $47 billion, say the Bitcoin Cash upgrade, with each software block growing from one to eight megabytes, will allow the currency to make a greater impact on the financial world. But traditionalists say the fork could sow confusion — and possibly hacking — keeping Bitcoin from penetrating mainstream markets.
