I think i ll wait for 100 K and convert in sats.
I ve a premium membreship (8wof a day) . but don t know if is profitable play the hi-lo game for earn more rw point with 1 rw point for 0.00000500 BTC i wager. No?
No, it's not profitable. At least, not on long run. When you start playing the HI-LO game you are likely to make some nice profit, especially if you have a decent bankroll size, but if you play for too long, inevitably at some point you will hit a long loss streak, and all the profit, plus extra RPs you made will vanish due to facing several losses.
If even aware about it you still want to play the game, make sure to wait to play during the promotional days, that is when RP rewards are x4, what means that for every 500 satoshis you wager, 4 RPs are going to be received, instead of 1 RP in common days.
Good luck.
