Hasmart has some drawbacks that are not related to changes in cryptocurrency rates or the benefits of cloud mining. Firstly, there is a serious shortage of contracts. Only two cryptocurrencies (BTC and ETH) and two types of contracts (fixed-term and perpetual) are available, and among the fixed-term contracts, there are only annual ones. There’s no point in discussing variations in mining algorithms. Secondly, there is a high withdrawal threshold (0.01 BTC). If you are using a small amount of power, accumulating satoshis will take several months. Otherwise, everything is at a decent level. It’s worth noting Hasmart's favorable geolocation. Thanks to its location in Siberia, the company saves on cooling, and the cost of electricity there is lower than where I live. If I were mining at such capacities at home, I would pay more for electricity than Hasmart charges for the maintenance of a perpetual contract. It’s also nice that this is honest and transparent mining. I don’t see signs of a financial pyramid in the project (even considering the presence of a referral program), and I have been participating for over a year now.
