> That's not really true. It may not be everyone's cup of tea, and speculation may be driving most of price, but these are real tech products. Ethereum, Cardano, Avalanche, Solana are decentralized computing platforms, with utility. Uniswap, Aave are exchange platforms, that allow people to swap currency real time.

That is still speculation and most of the existing financial system can do payments (the supposed original use case) already.

Take a look at UPI, Pix, etc. A safer, faster and better future of payments is already being built and used to the tune of hundreds of millions of real people. And it is not a complete pyramid scheme.

That cannot be said for crypto, nobody is using it for anything other than speculation, crime and ransomware.
