Talking about the last 90 days profits is unfair, you know that particular time frame was especially favourable to investors. Long-term expected returns are lower than that.
Hm, I didn't try to be unfair. I just picked a reasonable sounding timeframe. I just tried a few others:
30d investor profit = 393.06 BTC = 13.10 BTC/day
90d investor profit = 533.50 BTC = 5.93 BTC/day
180d investor profit = 770.41 BTC = 4.28 BTC/day
365d investor profit = 1,992.74 BTC = 5.46 BTC/day
