Bitcoin is a deflationary currency by nature. It was unique in implementing this idea until the altcoins came to be. Satoshi's invention will be like the lighbulb, world changing, revolutionary, widely implemented and spreading into new markets years after the inventor's death. Anyways, I believe that bitcoin will follow a base uptrend indefinitely, be it lineal or logarithmic. I believe that there is a floor at $100. we will
never again see double digit bitcoins (unless you scam someone out of their bitcoins).
We are at the end of the beartrend since the ATH. We can see now-obvious bottom of $150. The price has only been moving upwards since last month (after the week of absolute boredom both bears and bulls suffered through). The next halving is coming, just one year and 6 months to go, we've all seen the speculative boom Litecoin went through. Litecoin's price
tripled its price since may. At the moment, Litecoin is trying to break part the $4 mark. Bitcoin
will go back above $300, it's only a matter of "when".
At the moment, the best case scenario for bears (that is actually possible to happening). Is no movement upwards until 2016. By bitcoin's deflationary nature, and seeing Litecoin's undeniable revival (with a debatable lifespan after the halving), the most bearish scenario that I can think up (that has a realistic chance of happening) is a perpetual repeat of what we've seen since january 20th of this year (failure to rise above $300 and failure to crash below $200) until 2016, followed by a push up and beyond $1300 (peaking somewhere below $4000 sometime 2017)
TLDR: This is the "best" the bears realistically can do:
