I've been asking for positive examples for years, and I still see no signs that Bitcoin is poised for more than niche adoption. Sure, if you want to do something modestly illegal, like buying gray market prescription drugs, Bitcoin may fill a niche. But it hasn't caught on for legal transactions, and its traceability makes it bad for seriously illegal activities. And even if you're only doing something modestly illegal, you have to be pretty technical and pretty dedicated to make it work. For most people it's way easier to give cash to their friendly local drug dealer.
So yes, it doesn't have strong fundamentals. The underlying commodity, long integers, is freely available. Despite years of "Bitcoin will be widespread soon" puffery, the use value is very weak compared with alternatives. At least you could plant tulip bulbs.
