Start with cloud mining if you don’t feel like buying noisy GPU’s or ASIC’s and dealing with high energy costs? Buy your mining capacity at mining pools like Genesis Mining or Hashflare. For cloud mining or cloud hashing, you use the hardware from the provider’s data centers (miningfarms) to mine your desired crypto. It can happen that it is not possible to sign up. The most common reason is that the company is already running at full capacity, but not during bearish months or years when mining is not profitable. That is the best time to set up an account.
Keep in mind to do your research and watch out for scammers who do not offer and provide what they promise. Check out online reviews and find out which provider suits best to your needs and wallet.
