Super insightful! From the initial post @jacekw , all the replies, and @yabapmatt explanation. Seems beneficial to have TWO values: the existing Collection Power for quick calculation and ultimately reward ROI; and battle power which may need updating once a day or so to help ranked battles, perhaps tournaments, etc. This could be something Kiokizz, PeakMonsters, or MonsterMarket could probably do right now? At least to start tracking it. (don't intend to sign folks up, I just admittedly have no skills in this area)

I believe this discussion will keep coming up because a fun crypto/blockchain based game has two appeals: the gamer looking for a fun game, and the investor wanting ROI. The core player base seems to value both - and are being rewarded in both areas very well. However, mass adoption will require appealing to the former more than the latter, especially further out the ROI curve.
