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
The market is very down for all the crypto currencies and those who had brought bitcoin at the month of December and November when the valuation is quite good, are now holding their bitcoins and no one is now bother to sell their bitcoins and moreover the best thing the people are not even interested to buy more bitcoins because they have news that at low valuation if they buy bitcoins then in future, the market may crash also and I think this could be the reason for more red days than green days.
