I agree with your opinion, you will have no issue or problems holding Bitcoin, these cloud minings are suspects because they cannot sustain mining at this point in time after the halving, some small miners are already selling their mining rigs a clear sign that mining is not for everybody and that includes cloud mining which is actually Ponzi scheme.
If they do some research regarding on how those mining things works for sure they will be turned of for the returns given from this business option and for investment for sure it will give the same reaction since how could the cloudmining earn while the real one cannot even get a profit for their rigs so by this is a clear sign that people should avoid cloudmining since they are running a ponzi scheme system where for sure they will turn scam. I would rather buy bitcoins and hold since it will give more better result than investing at this type of bad option.
