Cryptocurrency Mining Opportunity
As I started researching Ethereum mining, I discovered how horribly wasteful it was requiring competition among miners which burns up the majority of the time, power, and computing power into an unnecessary race to make the next block which most lose at.
In continuing to research other mining opportunities, I found most to be similarly based on the idea of competition. Some clever systems bring in affiliate marketing and essentially force users to constantly reinvest profits in upgrading to keep up with hashing power demands. As with many business models, the top affiliates and the company make nearly all the money while most users are lucky to get their initial investment back and take all the risk with the promise that in six months they might break even if the current high prices do not drop. If the prices do drop, the users essentially lose everything as the hashing power now is worth almost nothing.
