As awareness grows, so will responsible practices and regulations. It might seem slow now, but each discussion, each project, is a step towards a future of widespread crypto adoption.
I don't really like relying on regulation to improve the rate of adoption. Not to mention people can already run their own payment system with open source software without giving any personal data. I believe the key issue is the technical side if we're talking from the seller's perspective. Other than that, I do believe Bitcoin already reached its goal as a trustless payment currency that doesn't rely on central authorities to issue and confirm new transactions.
Sometimes I wonder what kind of future are people looking for when they mean "world-changing tech" or "mass adoption". Is it being able to pay for your coffee with BTC in 1 second, use your BTC on your toll-gate without relying on fiat conversion, be able to live with your BTC on a remote island, or something else? It doesn't help that sometimes they just lump different projects together without explaining the developer's ideas when they start the projects.
