The markets aren't rational. The only thing we know is, Bitcoin is programable money, and only what's programable and can evolve with times will be sustainable and have real growth. Even if all markets are manipulated including Bitcoin, there are higher reasons to believe in the future with a Bitcoind mindset than a oil or Visa mindset.
I don't know man, I find that approach pretty optimistic.
Assets that are "doomed" don't usually reach all time highs in the way there. I might be a pessimist, but with Russia looking to ban bitcoin transactions related to FIAT I feel like bitcoin's market has a total disconnect from the real world. Some Chinese exchanges are also pointing out that their recent increase in traffic could be related to a ponzi scheme, which I think is exaggerated to a big extent but can't be 100% fake.
