This is a great time to invest if you can afford to at all.

That said, I generally prefer alternative methods for consensus instead of proof of work. Unless you're putting all that electric usage to work actually accomplishing something the way SONM does, why be so wasteful?

But I know that mining some coins that can be mined with a simple CPU or GPU democratizes access to crypto, because people in many countries have a hard time being able to invest in crypto with fiat. They have already been locked out of fiat, so we don't want them also locked out of crypto.

This is one of the reasons I love Steemit so much. Here you can earn STEEM with "proof of brain" so everyone can participate, and energy usage is minimal.
