Bitcoin holders don't actually care about proof of work or proof of stake, or even any of the technical details.
They only care that their investment goes up in value. That only happens if new entrants to the crypto ecosystem choose Bitcoin over alternatives.
Cryptocurrencies are like MLMs for nerds. The earlier you get in at the ground floor, the more valuable your position. You can help the price go up by convincing your friends to invest, who will convince their friends to invest, and so on.
Keep sleeping and balking at PoW. Stellar and Cardano will reshape the future of fintech transactions.
