It is too early to be very positive about current prices. It does not show long term rise to higher points.
Just hold your breath guys. It is still early. Be ready for downwards trend.
Nothing the comming year 2016 will show what the price is up to in the very longterm. Currently everything you see is short term.
Every long term starts somewhere. It could have started right now.
A solid and stable uptrend until in June we have an huge panic selling rally pushing Bitcoin to 5K a coin is perfectly possible given the current coordinates. I might suggest that you keep stacking Bitcoin at any price under 500 dollars, then start buying slower but steady.
Bitcoin community in a nutshell: price rises 30%, suddenly people are talking about how "reasonable" or "possible" another 1500% rise is. Stay grounded in reality my friends!
