can any one explain why this pump??
someone told that bitcoin hard fork is coming that's why this price pump .
There is no hard fork coming. I think what will probably come is a soft fork which is Bitcoin Silver. I am now waiting for some more updates on this since the news that first came out were at best fuzzy and vague. But I think more than the fork coming, the top reason why Bitcoin is seriously pumping in the past weeks is that the demand has really risen to an All Time High. There is no other to take for Bitcoin but really up since the coin is very limited and the demand is increasing every day.
