I think the problem is you're looking at cryptocurrency with the wrong perspective, so you're missing the fundamental ways it can rewrite the entire world of finance. I imagine you're looking at this from a consumer perspective, and you trust your bank, have a stable government fiat currency to use, and a credit card to make easy transactions with, so you have little use for cryptocurrency. Yet with the internet you likely saw the immediate ways you could make use of it, or how Google or Tesla would change the world with better search or better cars.

Cryptocurrency at the core is about solving trust issues and human coordination issues. Just because you don't have these issues in your life doesn't mean they aren't extremely important for the world. Part of the problem is that at times crypto has been sold as a consumer technology, remember before Bitcoin was digital gold it was going to be the microtransaction currency of the internet, which excited a lot of people looking through the consumer lens. But in the bigger picture of how revolutionary the technology is, microtransaction are the least interesting thing it could do.

This is a brand new technology that can solve trust problems and allow global business and trade to work more efficiently. It can allow humans to organize more efficiently and create brand new kinds of institutions (DAOs). Take Uniswap as an example. It's a decentralized exchange running on the Ethereum blockchain that has at times done as much daily trading volume as Coinbase. Now here's the kicker, they have two orders of magnitude less employees than coinbase (15 vs 1500). So not only are they vastly more efficient than legacy exchange technology, they also solve the trust problem because there is no third party taking custody of your funds, it's all done on the blockchain.

Another interesting example I've been pondering lately is automated insurance policies that run on the Ethereum blockchain and payout based on decentralized oracle data feeds from Chainlink. Imagine a farmer in Africa who doesn't have access to crop insurance, but needs to smooth out his year to year risk so that he doesn't go bust during a drought year if his crop fails. You can now write a smart contract that takes data from a decentralized oracle network providing rainfall data. A user can then pay into this contract and he will automatically be paid out if the rainfall during the growing season is below a certain threshold. So the farmer gets a slightly lower but much more predictable income stream. Someone else (who's better capitalized) can take the other side of the bet to collateralize the insurance policy, and earn a higher but more volatile payout.

This kind of efficiency per employee was never possible prior to blockchain. It's like how software and the internet allowed greater human coordination and orders of magnitude efficiency gains over legacy business organization, just applied to the world of finance. In the same way those massive gains in efficiency are allowing software to eat the world, crypto will eat the world of finance. This is a deep back end technology, and it's likely that by the time you're using it you won't even be aware of it as centralized institutions will adopt it on the backend while still providing you with a familiar user experience.
