Again, I'm not a BTC fanboy, I don't even own any. But obviously it solves SOME problems - like how to transfer some sort of store of value across borders without using a bank. That's one of them.

It's not tulips and 100% useless. A digital currency is interesting to explore. It's interesting enough that institutions are stuffing their cash into it because they are fearing inflation, and the old school explanations of why we won't get inflation are now being questioned.

Don't ask me to forcefully argue for or against, there are many other people on this thread to argue both positions. But you can't say it has NO utility.
