I have stayed from cloud mining because people talked that most of them are scams. Well, there are trusted sites before, but I read that they are also turning to be a scam. I want to invest and see if it is really profitable as other has confesses, however, I used my common sense and judgement not to, so I think I have made a good decision.
Cloudimining is too risky because of too many scam scheems so it looks like mining definetely isn't something that could be recommended. Unless you have a mining farm. So, stick to trading.
This is also thing of the past, solo mining is not profitable anymore. But I don't know, I still seeing people buying antminers, are they are doing solo mining or what? Trading is the only viable option for us to really make a lot of bitcoins. Solo mining is only profitable in the beginning, we have heard countless early adopters who have started to mine bitcoin and turns to be a millionaire. But now its not the case.
