It's not weird. The problem is that at some point bitcoins must acquire an unambiguous intrinsic value which is not related so much to their possible future value. If they don't, that's the definition of a bubble--prices that are considerably higher than intrinsic value.

Consider tulip mania from the 1600s. Speculation drove up prices of tulip bulbs to the point where the only people buying tulips were other speculators who were willing to pay the high prices because they thought they could sell it for more later on--the exact reasoning you just posted. Speculators were just trading tulips--or worse, tulip futures--amongst themselves. When the time came to sell the tulips to people who wanted them for decoration, it was discovered that none of them actually valued tulips that much, and the bubble popped.

There are arguments for a bitcoin having an intrinsic value of $100k. If bitcoin were ever used for, say, something as large as the real estate market, it would be hard to imagine the price being any lower than that. But bitcoin is extremely far from being used as the dominant currency in any market that large.

I think it's naive because NO investment offers that kind of return. People looked like absolute fools for trusting Madoff to give 5 or 10% or whatever it was, now theyre expecting 1000% just because this is "computers.... the future!!!"
