10 years of whatever this has been

I get it, it can def be discouraging. For me, I really _want_ to know what the great problems of the day are that bitcoin/blockchain can solve (or assist in solving). I imagine many others are too. So far, from my cursory reading, I haven't seen anything that makes it click, especially when weighing off against energy costs to our planet.

Ok I'll bite :).

Energy cost can be very low when using Proof of Stake. For example a 7000 transactions per second network could run on the energy of a single windmill: https://www.reddit.com/r/nanocurrency/comments/7ucw1a/the_en...

And for use cases, the second hand car industry is ready for disruption. You could say all blockchain use cases can be also handled by a central database. But this has failed miserably in the car industry. There are plenty of companies trying to log metadata, and as a result none of them have the complete picture. Even data aggregator companies are not able to properly bundle it.

Blockchain could offer a very good trustless solution, where you could log a cars history, and a second hand buyer could consult it.

Therefore, big names are entering this space, and I'm confident we will see blockchain solutions in that market soon.

This is only 1 example: https://www.ledgerinsights.com/mercedes-benz-blockchain-used...

The DHL website also has a nice explanation on their use cases https://www.dhl.com/global-en/home/insights-and-innovation/i...
