AFAIR, I invested in dice bankroll in year 2017 and it wasn't as profitable as I was expecting.
Well, we know that when there is a house edge, casinos will win all the time but don't expect you'll get big profit with your small investment and that discourages me because I also witness that there are casinos that goes scam and take the of the investors. (there's a lot of them, we can do a research)
with that experience, I decided to divest my money and invest it in altcoins and bitcoin and I am lucky I do it on the right timing and indeed it's more profitable than investing in a casino's bankroll.
Bankroll investment is something similar to traditional investment so you will get 5% returns per annum but in cryptos which can be generated even in a day so it all depends on what kind of returns we were expecting from our capital invested but one thing risk factor increases with the increased in returns.
