Is crypto actually useful?

I’ll try to keep it simple : try to think about crypto from the perspective of a no-coiner, you know, an everyday average Joe.

Apple makes phones, Spotify gives you music streaming, Chase keeps your money safe, KFC serves you chicken wings, Zoom helps employees communicate, but what the fuck does Solana do for you? Currently valued at 18 billion, but why?

How can my mom benefit from Solana for example? How can a company benefit from Solana? And how is it different from Avalance, Aave, Matic & the hundreds of other projects?

Remember, try to reply to me as if you were talking to a no-coiner, use real world example preferably.

Edit : I’m aware of the very obvious money transfer aspect, which is actually great yes, but there are hundreds of cryptos offering exactly that. So what does justify the existence of all these projects serving the same purpose?
