'Blockchain' has been the excuse for VCs and 'crypto companies' (ie scammers) to fraudulently sell tokens to retail investors, in a common enterprise, with the expectation of profit, based on the efforts of others. In other words, in an investment contract violating US securities laws. (That's why the SEC is suing them all).
'Blockchain' and 'crypto' is literally about creating endless supplies of tokens - worthless, often centrally-controlled useless tokens to sell to retail noobs... promising them that they can 'strike it rich' if they just buy at the right time.
These endless tokens on a 'blockchain' accomplish nothing and produce absolutely nothing... they aren't 'money' they aren't 'creating new technologies' they just 'go up'. They're not used even tangentially in 'real transactions'... sending, receiving, and holding... they're just traded to get more dollars on exchanges. Nobody really wants these things they're just excuses to trade to 'strike it rich' at the right time... while providing ZERO investor protections or transparencies, violating US securities laws.
These tokens and 'blockchains' have confused the public, given ammunition to regulators, and distracted people from proof of work and decentralization - Bitcoin's most important attributes. They've helped delay Bitcoin's MoE revolution, while promising investors huge returns actually resulting in... gargantuan losses. 'Crypto' is 99% worthless and goes to zero in Bitcoin terms over a long enough time period.
'Crypto' and 'Blockchain' have plenty of regulatory clarity - these tokens need to be de-listed and kicked out of the United States by the SEC for securities violations. THEN and only then can the Bitcoin/sound money/decentralized proof-of work revolution really catch on with the public.
The 'blockchain'/'crypto' scam following Bitcoin should never have happened.
