Nice observation. Yes bitcoins are exactly like tulips but moreso. In fact, in the future, bitcoin prices will drop below zero and these idiots will have to pay others to get rid of them. I'm looking forward to the expressions on their dumb faces when they realize they are in a pyramid scheme balanced on top of a bubble resting on top of a bridge over some swampland in Florida.
That would probably be the case if any of us were stupid enough to put our retirement savings or anything that we critically need into BitCoin. The smart money is on putting an early investment in, waiting till it doubles or triples then pulling the initial investment out. That way you literally can't lose - at the very worst you break even. Most people have put a quite expendable amount of money into BitCoin. Even without pulling it out, I could stand to lose my initial investment completely right now and not break a drop of sweat.
