Even then, I have to add the risk of the whales winning money and taking away a chunk of the bank roll. I've barely ever gotten a return investing in bitcoin casinos.
We all agree about the long term which is technically +1 year. However I am aware of 2 pro gamblers picking everyday up to 1 BTC and sometimes more which made the profits lately negative. Of course losing is a possibility but I doubt they will risk 22 BTC again
I see that whale win/loss big extreme event is still a hot topic here so I'll put a suggetion how to reduce their impact on final investment ROI.
The smaller the bankroll is, the greater your exposure to the extreme cases is (outcome from investment is more random). I mean that with infinite amount of bets the probability of you ending on loss in infinite low. So if you want to have the most consistent results even for short term investment (~1 month) you should spread your money between different coins and casinos.
F.e Instead of having 1000$ in yolodice bankroll that is 100 000$ big it is better to have 200$ in 100 000$ bankroll, another 100$ in 50 000$ bankroll f.e. bustadice, 100$ in 30 000$ DOGE etc. That way your 1000 $ is involved in much more bets/day. The closer you are to infinite the closer you are to infinite low probability of loss (i know it is not mathematically correct sentence, but it explains the relationship well enough
)
If bankroll that your money will be part of will be 10x bigger than you will reach less random outcome 10 times faster.
