I don't know about NFT, but blockains allows to me to send money to my Family in usdt/usdc for cents on the dollars, and for example in countries like Venezuela besides using it for receiving and sending money some people use it to save money because you cannot trust in the government and banks
That’s because organized crime provides the demand and liquidity needed for cryptocurrency. Without cartels and the like trying to bypass money laundering and capital control laws you would not easily transfer bitcoin to and from Venezuela.
