I stick at a stabilizing price around 50 dollars in 6 months from now, although it might end up as high as 100. This price level however is unsustainable. Bitcoin is getting more ancient with the day, with development being nearly non-existent and being overtaken by crypto 2.0. At some point, a lot of the people here that are religiously devoted to Bitcoin will realize that, but only when it's too late. The sad thing is that the people that will realize it too late will be the bagholders that bought at 3xx+ prices. Those people will take the hardest blows, without any opportunity to recover.
As for the short term: in 3 weeks time (before Chinese new year) we'll likely be back at 150, if not lower. Could happen in a matter of days, but we'll see.
I don't think the next big thing has to be related to crypto at all. All Visa/Mastercard/etc needs to do is develop credit card 2.0, having learned from Bitcoin's strengths and weaknesses. If they don't, someone else will. All people really care about is ease of use and the ability to dispute charges. As for the price, perhaps Bitcoin's true weakness is that instead of purely being a payment technology, it is a currency with a relatively small market cap. As such, it will be perpetually slammed with volatility. Instead of the technology making the headlines, it is the price. The cart has been placed before the horse ..
