I am honestly and sadly not sure why crypto is still a thing now. I am unaware of any significant or major product that came out of crypto except for all the "coins" and the NFT fad. I know that on paper, blockchain tech has great potential for security and bookkeeping stuff but I don't see anyone using it for that yet. Every time crypto comes up, it is always about some virtual currency that is notoriously difficult to transact and has extreme volatility.
Can someone explain to me why crypto is still a thing in 2023? Beside the "coins" reason?
