It must be killing that no one in bitcoin can launder money through fake buys and sells of useless pictures that can be downloaded for free anyway, even without having to understand what an NFT technology is about. Perhaps, had bitcoin had this technology implemented, regulators would have more reasons to hinder bitcoin's adoption. Thankfully, its scrypt language is too simple and unsophisticated to handle complicated ways of scamming. As for the difference between the speed of innovation in bitcoin and altcoins, I must say I am not surprised that centralized projects build things faster, more efficiently, and with minimum friction. At the end of the day, it doesn't require overwhelming consensus to implement new features in an altcoin, what you need is just a decision of the owner of a given altcoin.
