Investing in an online casino especially with the use of cryptocurrency seems like a no-brainer to me. The house win percentage seems small, but the amount of VOLUME is the key to success.
I also have traditional investments, but the rate of return is much less compared to the volatile cryptocurrency environment. It's like penny stocks with 100x more volatility, but if you choose the right one then the profits will be insanely rich in comparison.
I am not they type of person that will invest Bitcoin into any Gambling websites because they usually scam people for their money since they don't last that long.
Investing money into another cryptocurrency is a pretty good idea because the money that is made from that is large compared to investing in regular stocks, Bitcoin trading makes the money multiply if the person does his math correctly.
If I had to choose whether to invest Bitcoin in something or gamble it, I would choose investing it in an Altcoin to exchange it for more Bitcoin a little later on.
