I don't think that BTC's value would be that low. After a couple of weeks since the ICO ban in China the price of BTC from $4950.72 went down to $4319.72 in just a couple of days and went up again up to $4626.72. I think with the value of BTC getting low these past few days is due to the fact that the major players are adjusting to the ICO ban. Furthermore, the value will soon rise again after the market had already cope up with the changes. HODL!
