Cryptocurrency mining, such as bitcoin, ether, and dogecoin, isn’t as profitable as it once was. Here’s how to do it, as well as why small-scale miners are being pushed out of business.

Even dogecoin, a satirical cryptocurrency that lacks the same serious feature and institutional funding as bitcoin, has risen more than 50% in the last month as a result of a tweet from Tesla CEO Elon Musk.
