Druff, honestly, I think you have a higher chance of a better risk-adjusted return by just taking that "flier money" and increasing the size of your basketball bets that you've been doing. I honestly do. You might make more in bitcoin, but, I think you're risk-adjusted return would be much higher with the basketball bets...I think the odds of what you're doing is profitable are high even with that sample size and not knowing what you do. You should still be able to avoid a ROUT (quiting when you realize that you thought you had a good system but didn't), which you couldn't do with BTC if it goes into a true freefall.
BTC 9,761, but only because the next fool will pay that right now...could be 20,000 or 2,000 next month.
