Auto payout will be implemented on Friday. After that I will be making the "Last 24 hours" summary of BTC earned (available to all members). Following that update, there will be a second perk added at the 2% level, which is an email that can be received daily or weekly, which provides you with an earnings summary report in your email.
Will these reports be retroactive or only for newly earned coins?
It will only be moving forward. "Retroactive" reports would just be spitting out your current rewards summary. The report will be roughly as follows:
=== BTC Balance Summary ===
BTC Earned in Last 24 hours: 0.93859010
