Why is bitcoin going 3% up each day?
There could be several reasons for that;
1) hard fork
2) community is getting bigger and more people are buying bitcoins
3) to many hodlers no one is selling
4) someone is pumping it
5) All of above.
I agree, bitcoin community will growing up so fast that's why bitcoin value was grow up too. In addition due to high price of bitcoin in the market, more capitalist were attracted to invest because they were surely that bitcoin value will become more in demand in the future.
Definitely I was invest more today because I was expecting raising up bitcoin value for this coming days.
