It's not still early days. Bitcoin was created 13 years ago, it was useless for payments back then and it's still useless for payments now. Every direction that anyone takes it will be in the direction of some kind of pure money-making thing, usually in the form of a ponzi or pyramid scheme. This has happened over and over again for 13 years. There's simply no one else interested in building on this because everyone else can see that the technology is useless. The only way the scheme even works is because the miners are continually promised profits just for doing the useless "work" of running a node. If you take that away, you're left with an ordinary distributed database, and you can't use that to get VCs all excited with buzzwords and promises of instant profit, so nobody in the bubble does it.

We should absolutely throw away the bathwater. There's no baby. I'll say it right out. Cryptocurrency should be completely banned by every country on the planet. They have no purpose that isn't outright fraud and theft. Everything described in Podcasting 2.0 can be done with regular old Web 2.0 technology, and it can be done more efficiently that way too.

Edit to those downvoting: I will gladly retract this entire comment if you can demonstrate a single real, non-fraudulent usage of blockchains. I've been asking this for years and never gotten a straight answer. Everything is always "just around the corner" but every time I look around the corner all I see is more fraud and scams. If you really think there's something salvageable here, then let blockchains live on as a theoretical research project until somebody figures it out. In the meantime, please stop encouraging the general public to put their money into this. It's irresponsible to raise money this way.
