As I see it we have some good indicators
1. Very long bear period that must end someday.
2. 1w log chart has an EMA that clearly gives a bull signal and has held for >1 week.
3. Optimism in the media and forums
4. >5 year Existance of the currency
5. Halving coming
6. More infrastructure and investors
Etc.
Buy your bitcoins while they are cheap!!!!!
As for the halving event, that is definitely the fundamental event of 2016 for Bitcoin, but I hope to get some more fundamental support to fuel the next leg up. I still think it is too early to speak about halving effect at today's price level, but soon it will get noticed.
Bitcoin cant go down, that would look really bad. People won't buy if they knew the possibility of it going around 200s 100s so it will be a stale mate. Vise versa is people would buy up all the cheap coins because media only works so much.
What I mean specifically is that all these investors and startups around it are pretty big people, I doubt they will let it look like that.
