I use RRMines services. RRMine's decentralized computing power platform has a variety of products, In addition to the 3-year long-term contract, lock-in period of 30 days, 90 days, 180 days are also available. After the end of the lock-in period, users can freely trade or renew their computing power contracts. The contracts can be transferred to other users or repurchased by platforms then users can recoup their costs for buying contracts. A fixed investment will get you a more stable income, and you can choose to sell mined BTCs when the price is right for you. Also, you do not need to know how to set up, operate and maintain a crypto farm, they will take care of them all for you, its more of an investment instead of a technological challenge. they've a large userbase of 100,000+
There lot of cloud mining becomes a scam service, see what happens with hashflare, and I'm using their service when I interest in crypto for the first time. When I read some of the suggestion from an experienced member in this forum, mostly suggest user stay away from cloud mining. if you want to mining, better to mining with your own mining hardware. Or, simply to invest in Proof-of-Stake coin if they are (newbie) want to get some passive income, but this is also have any risks, DYOR/DWYOR before deciding to buy any of PoS coin.
