Bitcoin is not in a bubble because you cannot have a bubble BEFORE Wall Street (and the banksters) arrive. They are the ones who create bubbles.

Many claim bitcoin is too expensive and too slow. No it is not. Yes when compared to Visa for a cup of coffee, that is true. Yet credit/debit card transactions in the US account for only 3% of the total money transferred. 80% of it goes through the banking system. Why do companies send payroll in on Wed? So it is in people's accounts by Friday? That is almost two days. And what does Paychex charge? 2%? 4%? A lot more than the 20000 satoshi bitcoin costs.

Finally, Wall Street is entering this market and bitcoin is their darling. A great deal of that money will find bitcoin. In the end, the fact it is so well known only means that it will get more funding.

This is a great post...thanks @nutela.
