Crypto market is up 800% since January... I don't know anybody that bought cloud mining power and got back the amount they invested plus 800% growth in 8 months.... Maybe it will change in the next years but at the moment buying and holding is much better...
When i started counting what i found is that in order to by the coins in one go it would cost 2 times more expensive then to mine them, its just that if you mine them it takes you longer to get them. So you still benefit from all the growth just takes you longer to collect everything that is yours. But that is if you are not in it to trade.
