Yes you are right very useful but just few peoples can do good analysis and research and most of other creating rumors
Here's some analysis i did.
It covers the entire price of BTC from mtgox back at 5c a coin to the present day.
The non parallel log channel indicates relative volatility is decreasing, as expected in a growing market.
By march 2016 ±3months we may see:
- less "bubbles".
- the log rise transitioning into asymptote to saturation.
- $40k per coin ±$20k.
Very bullish but what will make a BTC be worth 40k$ are real things happening in the real world : USD losing its value, people understanding they are brutalised by the state, people losing their faith in the financial sector
not all of the pages I did read but
