I invested about $400 in cloud mining. So far, I’m watching the results with interest and plan to increase my capacity. However, it seems that recouping my investment will be difficult, as Bitcoin is unstable and is likely declining. Therefore, if you decide to invest in cloud mining, it's better to do it with larger amounts. I liked this service because it offers a lifetime contract, unlike many others where you rent equipment. Yes, there is a maintenance fee that includes electricity, cooling, and the staff's work at the data center, but it’s quite small, and the income is significantly higher. Bitcoins are mined daily, and you can withdraw funds once you reach the minimum amount of 0.002 BTC (but my capacity doesn’t allow me to earn that amount in a day yet). The money is credited to the account with a slight delay — what was mined yesterday is credited only today. I received a payout once, and everything came quickly and in full.
