I have a contract with Hashmart for a year, and at its end, I plan to switch to a lifetime contract, as cloud mining in this service is currently showing excellent results. The terms of the annual contract suit me perfectly: the price is almost half that of the lifetime contract, and there are no maintenance fees. However, for some reason, annual contracts for Ethereum are sold out right now; a friend tried to get one but couldn't find it. This is strange, as lifetime contracts for Ethereum and annual contracts for Bitcoin are available. I'm satisfied with the service's prices: they offer reasonable rates for power, don't deceive, and transfer payments to the account every day in full. Overall, they operate honestly. Of course, net income has slightly decreased recently due to the drop in Bitcoin and Ethereum prices, but over the past six months, I made good profits during their rise. How the investment in cloud mining will develop further will only be shown by time. However, at the moment, it is still relevant, so you can confidently get in.
