I also think those calling for a bubble are only calling for trouble.
Who in their right mind thinks ANY business that sees the price fluctuate 10-20%+ in a day is going to want ANYTHING to do with btc? Plus with the losses a lot of people incur naturally when the bubble pops, it creates an overall NEGATIVE image and outlook for btc in general
I'm not calling for one, but a revisit of $500-$600 is certainly possible before the end of the year.
Technically the market is ripe for a rise as most of the weak hands have sold off their positions and the quality of ownership is quite high. People forget how relatively few people are into Bitcoin right now, much less buying large amounts. Those buying at these prices are institutions, professionals, whales and traders looking to ride in their wake of accumulation, which creates a temporary shortage (aka rocket launch pad). They won't be selling until a % of the gains lost in the bear market are recaptured.
Bubble territory would be far above the ATH, like $2000+. That will only happen if the bull market attracts a significant amount of money from the general investing public. Unfortunately this happened during November 2013 as (IMO) most of the rise past $800 was from the greedy public for a number of reasons You cannot stop people from being greedy and fearful, it is a trait of human nature and markets will always be full of them. Like it or not Bitcoin will see some wild swings until its market becomes larger and more mature.
