Try to use cloudmining site but its risky 
It's not so risky as gambling or other stuff and also now people trying to work with trusted sites. Maybe cloudmining is the best way for newbies i think.
it's better than you use gambling
I don't trust cloud mining as I don't think it can be profitable in long run, and its difficult to judge their genuineness, may be it will disappear in future, better option would be trading.
you are right to not trust cloudmining services most of them are not legit, they are just taking money from new investors to give to the old ones. but there are a handful that are legit but they also have bad ROI.
the only thing that was good once, was cex.io that i have tried and i wonder if they will resume their operation when the price rises because they have paused it because of low price.
Selling on the right moment will be the best thing to earn money but you can also trade or gamble but that is more riskier.
