There's a huge wave of dead bitcoin-related apps that I'm currently tangling with. I suppose they're still the remnants of the FTX and Crypto Winter phenomenon of late.
It's a brutal evolutionary mechanism that turns the crypto-billionaires of yesterday into runaway fugitives with hardware wallets up their asses.
Many of these apps are actually foreign based in formerly crypto friendly countries.
The ones that do survive - actually do put Bitcoin to good use: remittances, bill payments, mobile load, etc. They compete with fiat apps that do the same job minus the advantage of a blockchain.
