Does Bitcoin have any logical legal use?

[I spent the winter writing songs about getting better]

Right now it's fundamental usage is for illegal transactions for obvious reasons (kind of a throwback to Flooz if anyone remembers that, which ended up primarily being a money laundering tool for organized crime.) The only other reason I can possibly see someone getting into it is to cash in on the bubble and make a profit.

Now why anyone would prefer using it or setting up a system to accept transactions in it for legal purposes is beyond me since the only reason I can think of is "OMG MONEY NOT CONTROLLED BY THE EVIL GUBMINT!11!! END THE FED!!!11!!!" Which actually is basically the reason it exists.

So basically it has no purpose but for illegal transactions, to assauge libertarian paranoia, and so that others can make a profit off the idiots in the former group.

I'm inclined to agree that Bitcoin is a pyramid scheme. I just wish I had bought a few when they were 10$ (I almost did). It's probably too late now to profit off the bubble.

I'm sure once it crashes there will be enough morons to drive up another bubble again, so there'll be another opportunity.

Not surprising. Another problem with it, this can easily happen and if invested there's basically nothing you can do. You're basically buying something of dubious value by giving actual money to shady characters and then trusting others with dubious value you've purchased that if they decide to take off with, you are a completely screwed.
