Everytime there is a stability in the market, or a small downtrend on a short period, these questions come back. Is it loosing popularity? Was it just a bubble? Is the bubble dead and so on.
My advice : look at the big picture. As everyone mentionned here, more people know about it. Businesses are accepting it more widely. Soon might go in NASDAQ.
It will explode again. Or keep rising eventually. Just stop looking at the charts every minute.
