You have a point, the market is indeed irrational and the smart guys make money out of it. Honestly I don't even think BTC itself should be worth 17K$ at all. For the simple fact that I don't want to pay a 10$ fee for transactions. On the other hand lots of crypto's which are actually useful go unnoticed, like BURST the first PoC coin, DeepOnion offering something unique called DeepVault for file validation, etc.
