Another thing is that, AFAIK, generally these bankroll investments used to be profitable before but I guess they've also changed a lot even if the market is turning bullish lately.
Yup, they used to be a big thing, but nowadays I'm only aware of 2 sites that allow BTC investments in the bankroll.
Strangely enough, them being less "popular" as investments, can make them more profitable. It's all about the wagered-to-bankroll ratio after all.
I suspect stats for BitVest presented here:
https://dicesites.com/bitvest may not be accurate, but if they are, it looks pretty interesting:
I'm too lazy to manually calculate the daily/monthly wagered average, but assuming it's about 7btc/day, HE is 1% and the total bankroll (per dicesites) is 78btc - this gives:
(
BTC7*0.01*365)/365=
32.8% expected annual yield. And that's in bitcoin, which is likely to appreciate in value on its own in the near future.
Of course this is overly optimistic, as low HE sites often have a hard time to achieve profits at expected levels + this doesn't account for investment margins. But still hard to ignore.
So it mostly boils down to how trustworthy and reliable the owner is. Sadly, such sites tend to be one-man bands, so if something happens to that person, it all falls down.
ps. is anyone invested here and cares to share what are the real returns?
