If you are a crypto newbie and someone is shilling cloud mining beside you do not give them your ear, no single cloud mining is real they are all scam, a relative came around yesterday and luckily he opened up to me, I stopped him from depositing money on a cloud mining website, they never pays and on the long run they will exit scam on you
If you want to mine, buy your mining rigs (GPU cards) or ASICs to mine with your farms.
Cloud mining is risky because you don't own any rigs and you must trust the cloud mining services for the capital you pay for to loan hashrate. It used to be one of most common scam.
Cloudmining 101 (ponzi risk assessment)With real mining farms, it is risky as well if you buy hashrates because you don't know when the service owners will run away.
