I've notices most people opt to invest in cloud mining. I have reasons not to like cloud mining. Most cloud mining companies run ponzis, even if they have a mining farm , the funds that people deposit as investments are only use to maintain or upgrade their mining farm. When new users join they pay the old users. After all their machines are always running 24/7 it's not like when one purchases a contract they then turn on one of the machines to start mining. be carefull of cloud mining.
