Is cloud mining profitable?
The answer to this question depends on some factors that affect the profitability of investments. Cost is the most obvious factor. The service charge covers the cost of electricity, accommodation and hardware. On the other hand, the reputation and reliability of the company is a determining factor due to the prevalence of scams and bankruptcies.
Finally, profitability depends on factors that no company can predict or control: just remember the high volatility of Bitcoin in the last three years. When you buy a mining contract, it is better to assume a constant price for Bitcoin, since your other alternative is to buy bitcoins and wait for the price to rise.
