Stop comparing #bitcoin to tulips. Tulips lack many essentials qualities of money: Durability, Divisibility & Uniformity (which BTC has). Gold is a much more accurate comparison (though imperfect).
Pros of gold: long history & non-monetary uses place a floor on value (won't go to zero), helps holders feel safe. Pros of BTC: more transferable, divisible, can grow in features. Con: could be replaced by competitors and become worthless.
The skepticism is good. It helps prevent Bitcoin going nova immediately and freaking governments into ill-considered but draconian policy action.
Tulipcoin is not a viable means of exchange or unit of account, it's too volatile. Your three qualities are essential but not sufficient properties of money. No business will use tulipcoin and potentially have 80% of their profits wiped out by currency fluctuations.
