I wasted years of my life in crypto

It's good to know everyone here is weary of crypto scams, but I don't see anyone accurately describing the significance of these technologies.

Bitcoin failed as a currency, and as that became realized, institutional investors pivoted to the "digital gold" scam, to keep people long, while they divest or hedge. The two reasons why it failed as a currency are transaction latency, and lack of fungibility. Transaction privacy is necessary for fungibility. Both of those are just technical problems; I predict that a distributed ledger currency with private transactions like Monero, but a faster consensus algorithm like Avalanche or Hedera will become popular in the next decade. It's likely to be an Ethereum L2.

That is just the currency aspect of distributed ledgers. It's just one use case that we don't yet have the technology to properly address. The exciting thing that distributed ledgers enable is cryptographic institutions. These technologies allow us to solve coordination problems more easily than ever before. Democracies, businesses, communities, projects can all be coordinated better and more honestly using distributed ledgers. It's not an overstatement to say that distributed ledgers are as big of an advancement for human coordination as democracy was.

If you've been soured on these technologies because most of the currencies built with them are scams, I would encourage you to learn about them as if they were just incredibly robust databases that even governments would struggle to take down. Surely you can think of something cool to build with that, which doesn't involve money.

What's the incentive for keeping these "robust" databases online, if not for making a lot of money by running scams?

Imagine you have a home on Airbnb , your guest sends you a payment, but its not directly to you, the payment goes through the payment rails stipulated and controlled by airbnb. This amounts to what is often 25-35% of your listening fee (payment charges, visa network, listing fee, etc, etc.) This is the middle men crypto is supposed to replace.

Only a trustworthy network can replace the current system, it must be something public, immutable and participatory , otherwise it will just centralize back to the above scenario, regardless of any intent. Essentially crypto is network code, it creates the primitives on transmission. And thus anyone (really anyone) can run a node and get a reward for supporting this security model. That's not a scam or even just pragmatic, its literally how money operates, as a incentive/disincentive mechanism.

People forget the early stock market was filled to the brim with scams, the original intent was good, but it attracted bad actors piggy backing in its lack of regulations, and it took years to clean-up, one can make an easy argument that's its still filled with fraud.
