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.
I've never done it, but when I lived abroad and I had to transfer money, I got fleeced by banks and then (a few years ago) there weren't really any alternatives. I don't have any skin in the game with Bitcoin, but I guess that left a foul taste in my mouth.
There've been other comments about Bitcoin that are a bit more nuanced and interesting, in one case there was a gentleman from Argentina making an impassioned case for the use over and against the polices of his government.
I think there's an element of institutional mistrust that Bitcoin claims - maybe wrongly, given how centralized it is - to solve.
