Back in 2017, I actually considered getting an Ethereum tattoo. I'm so glad I did not. Now I still only have one tattoo, my bitcoin tattoo, that I got in 2012. It's the only tattoo I will ever want because bitcoin is the only money I will ever need. https://tattoo.glencooper.com

Proof of work is the only way that makes any sense.
