If you check a bit the altcoins world, there are a lot of token based on a really interesting and usefull purpose. The problem remain the same in every business. It'll gain value and fame only if people are interested in it.
If the project is great but nobody wants to use it, the principle of offer and demand is not matched, and the project (as beautiful as it is) will not raise.
You are quite right, and I do understand that usability of a project vs interest does not always (far from it) end up in a symbioses relationship. I also understand that many coins in themselves have great potential and systems/ideas. But it is the coins / systems themselves that is the potential, not the process that produce the coins. We are still moving dirt from on pile to another, for no reason what so ever, other than that produces coins.
Why are those billion Tflops mining bitcoins not curing cancer at the same time? They might as well!
In real life – setting aside a few government projects – nobody is getting paid for digging holes for no reason what so ever. In bitcoin universe I get paid for digging holes in my backyard, filling them up again and starting all over.
It is not like someone has to pay for it. I don’t not understand why we can’t solve some meaningfully problem / project, and at the same time produce coins? – Like they do in Gridcoin, hens the question, why is Gridcoin not a major coin.
