Web3 and volatile cryptocurrency have become so similar that we most of the times dont think of stablecoin being another part of the network.
Now those companies we know to be more of world class and highest in terms of revenues and market capture, those had the potential to build own coins and it indicates the strength of the company.
I think in web3,there would be similar companies that would seem influential like those above. Only future can show that and I hope that time comes within 20-50 years.
Not more than that period, maybe.
