i think if we know about investment in gambling, its a good investment but you still be careful when you want to make any investment. for me, i am lending some amount of bitcoin into market exchange and i think i am making some of bitcoin and i can see its really grow although its not a big amount.
Investment in gambling is good starting if you are saving bitcoins while waiting for the price increases , But make sure that you are going to invest on the right investment website that can live long run investment. Definitely although bitcoin price will increase but not that big enough but atleast we really can make profit while waiting.
but if you have no experience and no skill of playing gambling then it is really a very very foolish decision, you cannot depend on luck only, first you have to get some experience about gambling by investing a little amount and only then you can play gambling with high amount.
I never say that his going to play in gambling i say that try a good opportunity if he can't defeat the gambling site then join them this is a good idea earning money from where you lose before. you don't need a skills to invest money

simply find a gambling website that offers investment and then put your money.
Well, some time ago I analyzed the astonishing profits that Betking had brought to the investors in their bankroll, and it turned out that almost all profits within over three month period came in due to just two separate events, most likely big whales heavily losing. Therefore, even when investing in the bankroll, you are still very vulnerable to "the random nature of the games themselves", as one of the previous posters correctly noted.
