It is Rosetta required at all if it is supporting WCG? I started with rosetta but migrate to WCG so I could double dip with byteball-sparc-neummanium
Rob said future BiblePay release will not require Rosetta RAC at all. For now, it does. I think if you crunch one Rosetta occasionally (so your Rosetta RAC is never 0), you should be fine. I'm primarily 99% on WCG now for the quadruple dip, and to help with Thor challenge.
