"Niche but efficient"

@vel3vul is a friend of a friend :) He's successfully mining Bitcoin with the S19kpro and teaches newcomers how to get started. He also introduced me to the emerald card for everyday spending. I'm currently earning airdrop rewards through my grocery shopping and travel expenses. The account may be specialized, but it's very valuable if you need focused crypto expertise. I think there's a lot of potential there.
