The cat is out of the bag, with respect to blockchain tech. Bitcoin on the other hand? I wouldn't be so sure yet.
It's not possible to create a decentralized cryptocurrency, only ones that increasingly centralize over time. This means none of this garbage has any fundamentals and the only byproduct of this entire sector will be federated chains, aka the ones govt and corporations will use to try and enslave you. Some people on these forums are genuinely stupid and haven't figured this out, but many know this is true yet still promote bitcoin to try and defraud other random bums for pump and dump profits while spamming fictional Andreas Antonopolous bumper sticker slogans.
