One of my best mates holds 50:50 eth btc. 

I don’t want to tell him what to do with his money but I’m not an eth fan. 

Any tips on how I should kindly handle this?

Maybe there’s a good video or resource I could point him to? 

He runs a startup so has v little time, sadly. https://image.nostr.build/c7371e9528a6366c7dd75bd127fe3d5c14b23ab780bc9240facd2e10ec824f0e.jpg
