The technology behind cryptocurrencies and it's value as a financial tool to society has nothing to do with politics, tulips, its market price or any other of these arbitrary and ill-defined criteria constantly being trawled up in these debates.
In particular the comparison with tulips and constant obsession with it's market price is a total distraction from the technical innovation which cryptocurrencies bring to modern finance which is clear and unambigious.
That is that they facilitate direct asset transfers between peers *without the need for a counterparty*.
The only "tool" that society has had up till now which can do this is Gold. It's not a question of value and whether or not Bitcoin / Gold etc have *value*. Its a question of *function*. Monetary function.
