I can't see bitcoin existing long term because right now I feel the only thing holding it up is it's brand. People know the word "bitcoin" and I'd venture that for 99% of the population that's the only crypto they know. BTC is however, pretty objectively, a really shitty crypto. Which is fine, it's the original one, it would be crazy if no one hadn't figured out how to improve on it.

I just think it is a matter of time before someone hits the right social cords with the right crypto and the wind is sucked out of BTC overnight. There are certainly tons of people trying.
