The results of cryptocurrency mining highly depend on the price and the network difficulties of the given cryptocurrencies that you are mining. Neither of those are predictable and each customer must make an independent decision about the benefits of cryptocurrency mining and, in doing so, should consider the risks and their own circumstance when choosing whether to mine.
For reference, one source to potentially consider is coinwarz.com. Please note that the website is an independent source of reference and not related to Coinface in any manner.
When evaluating the benefits, you should note that the mining of some of our contracts is subject to a daily maintenance fee which must be deducted from any daily mining rewards you may obtain from mining using our hosted service. You will find the maintenance fee details of your chosen contract in the Terms of Service before the purchase, or via our Pricing page.
