Invest in a trusted site invest your bitcoins there and then it will earned a capital even you do nothing while investing you can do mining or gambling to have time to earn another that way you can bitcoin in a great ways and multi tasking way.
Investing money in cloud mining and gambling is very risky. In gambling there is no guarantee that you can profit and In cloud mining we cannot know how long it will last. I would prefer investing in trusted ICOs or trading unlike in that two.
Yeah although all forms of investment have risks, at least we know how much risk faced. I think gambling is not an investment, and cloudmining says it runs actual mining it does not matter although it takes a long time for ROI. But most of the time cloudmining is HYIP on behalf of mining. Better to hold bitcoin in the wallet, and may be occasionally used for trading. Thank you
Cloud minning is a total scam and such sites are made to scam people one day or the other. Gambling is too much risky to try. I only trade in bitcoin/ altcoins and get good ROI. I also think that trading is the only legal way to earn bitcoins, although it requires skills to be a good trader.
