Fair enough, it has some bubble characteristics. But surely you can agree that there are more facets and depth to BTC than most other bubbles (tulips especially)? I assume youre talking about BTC as an investment (the 'buy coins just to sell them, lets get rich quick' side). Id agree that is the aspect of BTC that is most at risk of 'popping' long term imo, but just cos the price is falling hard now its far from likely to be a 'popped bubble' failure - even at 10$ per coin people can get a good return with good trading strategy - as they do with other commodities & currencies.
In the broader sense,(at the very least) BTC as a technology is very unlikely to 'fail', even if it just ends up being a back end system supporting transactions where the banks/money transmitters 'rent' the use of system from miners.
Maybe you shouldve pick something from the 90's .com bubble that flopped to compare it to :p
As you said, lets see what history has to say:)
A bubble is a bubble, people buy in to it on the hope of it will be worth more in the future. I don't see a great deal of re-use in the technology behind btc either, yes its decentralised but it takes a lot of energy to maintain the block chain. Is this really the best way to have a global currency?
