> It is the epitome of a solution looking for a problem. I can't entirely agree with this. Originally Bitcoin seemed it could be a solution to a problem (i.e. decentralized digital currency), and it turned out it became something a bit different: a kind of digital investment that is highly volatile but has some advantages over, say, traditional stock (and plenty of disadvantages, too). So for a few people, Bitcoin did solve some problems - and created many problems for others on the way. Blockchain in general has proved to work for what it's been intended, that is not being able to forge transactions. Even though we don't have any really useful applications for it, it's good that it exists, because in 10, 50, or 100 years it will turn out it's a perfect missing puzzle piece for some invention we still don't have any idea about.
