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
Investing on the cloud mining site is not that really worth it because the earnings that you could make there is like what you could earn in the FAUCETS, besides, just like you guys what said, it is a very risky one, because there are cloud mining site which is a Ponzi one, while in Gambling, you could win big, but the risk that you are going to take is big also.
But if you really want to earn bitcoin is a legit way, which you could assure that you would earn money is the Signature Campaign here in this Forum for example, Trading, and the Social Media bounties.
