Congrats on winning some funding rounds, spend them wisely.

Crypto is great, but almost for all the opposite reasons:

• Smart contracts and DAOs, are the basis for a lot of financial instruments that would otherwise be a bureaucratic hell, properly used they're beneficial for both investors and clients.
• NFT tokens (yes, I know what I did there) are worthless without an external element to recognize them (whether automated, legal, or human), but they tie well into the "code as law" ideal, and are a good fit for other... well, code. That means stuff like actually buying and owning digital goods, instead of the "buying" (until they decide to take it away) that media/software platforms are currently selling everyone onto (now that's a scam). Or to be not worse, but quicker and more versatile, than a digitally signed notarized document.
• Decentralization is nearly worthless, except as the basis for independent verification of transactions. Whether they come from a more or less centralized source, is secondary.
• Self-custody is only for the really dedicated; 99% of the population doesn't need it, doesn't care, doesn't want it, and would more likely be hurt by it. Check out the PGP "web of trust", and Namecoin, for cautionary tales. Banks were created precisely to avoid self-custody, which used to be the norm before them. Also why the average person loves to keep all their data only "in the cloud".
• Apps don't need all to be OpenSource, decentralized, or audited; they can be private for a private purpose. Just don't use someone else's private app.
• The "web3", is a nonsense buzzword. A "decentralized" web is just called "the web", no need for any blockchains or anything, hyperlinks are more versatile anyway; the Fediverse or e-mail are "decentralized apps" working just fine, sometimes called "self-hosting"; token economy is simply called "economy"; storing data off-premises, is either "the cloud" or "someone else's computer"; nobody wants "unstoppable" apps, just apps that fulfill their promises, then stop wasting resources.

I get how attractive all the buzzwords and ideals are, particularly for someone interested in programming, but as someone else said, get a sense of how, and why, the current systems work as they do, then you'll be able to better separate what has some potential, from what's just buzzwords to blind you to what's going on in the back.

Unless, of course, you're up to don a sparkly suit and try to con others... but beware, there are people with decades more experience out there doing the rounds.
