SOL has definitely made a lot of people rich in a way that is not so much expected like memes but it's because it's fast and reliable (if there's no black out)
Neah, it's not the actual speed of transactions that has made those people rich is the hype around the speed.
Your average Joe won't be interested in confirmation of 10 seconds or 30 seconds when sending money, when paying for something online the times in seconds become quite irrelevant if you don't go to extreme like waiting for 20 minutes, and if we talk about purchasing in real life store....which store accepts solana?
The price right now is more because of the Bitcoin hype and the hype of what could be next for SOL, less on the actual capabilities and usage.
Cardano rode the same wave and then it was left with no wind in its sails.
