Downward market trend has been envisiage, base on the bullish season we experience late laat year 2017,no need to panic or sell of your BTC in your protfolio, we are sure to still take advantage of the moment.
Maybe a lot of panic can not be used, what is bitcoin if it continues, and I prefer that I can buy back bitcoin at a low price, and I keep it for the long term because I am optimistic that bitcoin prices will return like January 2017
