An obstacle to large-scale bitcoin mining is finding enough cheap energy to run the huge, power-gobbling computer arrays that create and transact cryptocurrency. One mining operation in central New York came up with a novel solution that has alarmed environmentalists.
NEW YORK (AP) — Walmart denied any partnership with the digital currency Litecoin after a fake news release led to a brief flurry of inaccurate reports from national news outlets and social media users on Monday.

No matter if crypto is going up or down, the best thing you can do is to not look at it. Set it and forget it like you would any traditional long-term investment account. “If you let your emotions get too much into it then you could sell at the wrong time, or you might make the wrong decision,” says Yang. “You stress out about it, and I don’t think that’s a healthy way to approach it.”
Altcoins also sometimes differ in the method of verification used to authenticate transactions. While some altcoins use Proof-of-Work systems, others use Proof-of-Stake consensus, which replaces miners with validators. Proof-Of-Stake mining requires a lot less energy and fewer resources than Proof-Of-Work systems since Proof-Of-Work miners have to do much more ‘work’ to mine blocks.
