I used to join cloud mining and to be honest, it wasn't worth it at all. Currently, cloud mining is not very interested anymore but there are still newbies who fall into the trap. I personally don't recommend you to invest in cloud mining.
Bitcoin mining is always used when they introduced by someone in to bitcoins and we can also see how mining is well introduce in certain videos about bitcoin so expect that there are newbies will fall for this classic scams since not everyone can warn people about how bad it is if we make it as option for us to earn, thats why its good to avoid cloudmining since its not really worth it and scamming is always the ending of the story there.
