Perhaps the downvotes were harsh (I was not one of them, can't downvote :), but the question was "what problem does bitcoin solve?". I'm having a hard time seeing any problem in the parent's comment. Instead of identifying a problem, poster is encouraging us to go on an adventure.

For me, I'm tired of really discussing it. I stated a powerful usecase before, but it seems a lot of HNers don't really want a use case, they just want something to bash on. So if you want use cases, you can look it up on the net. And if you want something to bash on, you won't get it from me.

  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_entire_nano_network_is_so_efficient_that/?utm_medium=android_app&utm_source=share 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-car-market/ 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/insights/blockchain.html https://www.dhl.com/global-en/home/insights-and-innovation/i...
