Hi Curmodgeonnette,To profitably mine Bitcoin today, you need an ASIC, i.e. a custom chip that does the mining. To mine Ethereum and other cryptocurrencies, you need a powerful GPU - the AMD Polaris series is a particular favorite.
Love the name. Thanks for the answer. Do you think contributing to this type of effort might support anti-state, or underworld financial activities. I know that people are ‘excited’ about the new ‘currencies’, but there seems to be such mystery about who is really behind any of them. I’m sure I sound ignorant...but you sound informed on this subject (from my perspective) — since You know how to ‘mine’ it!
