Nowadays the Bitcoin's price dropped to about 600$, so i don't think that the price will going high quickly to reach 4000$, at least in the nearest future
This is right. bitcoin price is dropping very fast. I don't understand what is the reason of bitcoin's price dropping like that.
now bitcoin price is 550$. and 4000$ is far far away from it. I don't think bitcoin price can reach to this mark at all..
bitcoin need more demands and markets.
The price drop is likely due to the large hack of an exchange in China. Something like 70 million dollars worth of bitcoins were stolen. Generally, hacks that large tank the price because it introduces fear and uncertainty in the market, which the market does not handle well and people flee to safety.
