Ofcourse here many numbers of the casinos are available to Invest ( you can see in most of the topics like moneypot cryptogame etc) .
But here u would like to tell you that this just risk like gambling , I would be more better to make Gambling with your bitcoin instead of Investment , Because if you will loss then all your deposit will.loss , but I the gambler loss then you will make a small penny of the earning .
So here this will be more better that you should give time for the trading , Just research about the best best altcoins for long time and then after buy put then at sell in advance , so in this way you will never face any problem that have no time for Trading . I am also doing the same as a side job with my teaching job .
