The best cloudming websites are for me not even relevant anymore because of the fact that these websites are mostly ponzi's..
I don't think cloud mining is legit mining sites nowadays because most of them were scam and mining actually is not profitable these days because mining hardwares consumes more electricity, and you only mine less efficiency due to it takes long hours to mine and yet electricity is expensive for those hardwares.
it is why I have now a cloudmining site without miner...no miner = no mining hardwares electricity consumation (lol)
