All things being equal, there is no reason why one virtual currency should be worth more than another.
Tulip mania and bitcoin mania are both caused by the delusions of some folk. It's entertaining to watch from the sides but don't gamble on it, its trend is definitely down.
First of all, please don't give financial advice. I know you're just stating your opinion, but when you "tell" people what to (or not to) do, it's a form of advice that contributes to the very delusion that you referenced in your reply. I, personally, don't consider this downtrend a "gamble"; I've taken the opportunity to buy the dip at a firesale when Bitcoin was in the $6k's a few days ago.
Just please refrain from giving financial advice again in the future. Sorry to pick on you, but I figure one person at a time, and it could help stop the false hysteria that's being associated with Bitcoin. Cheers!
