The trouble is that these centralized entities came about when the tech itself was too nascent and there were no decentralized alternatives. So they had too much power and money. And now that they're crashing and burning, the decentralized alternatives can have their moment in the sun.
For instance, there's a dApp for leverage trading called GMX.io. Since it's decentralized, all of its assets and liabilities and treasury balances can be transparently seen by anyone. It offers most things that any large brokerage would offer, and has been functioning without a hiccup throughout the entire clownshow.
When I started out in November 2020, the decentralized economy was tiny and there were few dApps. Since then, there's been an explosion in the number of dApps powering everything from payments to digital asset market places to in-game asset trading. Paying for a digital subscription with a web3 wallet is a better experience than anything in traditional finance.
Of course there's a lot of fluff - that was inevitable given the wild excesses we saw in 2021 - but the pieces are in place to form the foundation of the entire digital economy.
I will be very, very surprised if you're still using your credit card to pay for things online in 2027.
