Hi there, are cloud mining or pool mining profitable nowadays? Which one should I choose do you think?
Neither are profitable. You would be better off gambling money in vegas than any hope on a ROI with mining nowadays.
Cloud mining companies are made up of ponzis, fractional reserve mining operations, and the ones that truly have all the hardware are so expensive they have to mislead their clients into thinking that will see a ROI.
I am embarrassed for the shills, apologists and affiliates who rationalize this disgusting behavior. This is one of the most embarrassing aspect about Bitcoin nowadays. Bitcoin isn't a ponzi itself, but there is certainly a lot of scams and ponzi's within its ecosystem.
You don't have to take my word for it , use any advanced calc with a releasable difficulty and see for yourself :
