Two days greenery then suddenly 4 days red. I think this happened due to money makers. Most are coming to money making from fluctuation. Because of this fud or any bad news there , these people get panic and selling their portfolios so the whole market crash.
But people like us , invest to the technology. What ever the thing has happen , we think that this has good future. so we keep our coins for long time.
This is my opinion. Why more red days and few green days
if you only see the average price graph per day I think that we can conclude try you see the price chart annually you will know bitcoin has a good enough increase per year
