>Other bitcoin alternatives have been less successful at limiting their environmental footprint. Chia, a cryptocurrency that is built on a “proof of time and space” algorithm, has been accused of leading to shortages in hard drives and SSDs, a type of storage medium popular in fast computers. “Instead of just wasting electricity, Chia chews through SSDs at a fantastic rate and also has thoroughly wrecked the market for big HDs,” said David Gerard, a cryptocurrency expert. This part is at least disingenuous. The real movement away from PoW is in PoS coins but all they say is that it 'ha[s] been less successful' citing the worst that has come out and from a small project at that, and mentioning ETH's slow move to it as if there aren't other projects already using it.
