As Market Watch says, there are three reasons that could lead to a brutal correction of this crypto-currency: First of all Bitcoin signs the return of financial bubbles, then it will certainly lead to overinvestment and a Wild speculation, and finally the bubbles always end up bursting. And these corrections will undoubtedly have unexpected training effects.
Bubbles are not a completely bad thing, the last dot com bubble brought useless companies, that is true but it also created some giants and the interest on them created an incentive to adopt the internet even faster, and I think the same is going to happen with crypto.
