Bitcoin price has now dropped 20% toward $4,000, three days after hitting an unprecedented record high of $5,000over the weekend.
The price of bitcoin hits a two-week low in a decline following China’s ban on initial coin offerings (ICOs), a radical new form of fundraising where digital tokens are exchanged for cryptocurrencies like bitcoin and Ethereum.
The early hours of Tuesday saw bitcoin value drop near $4,000, trading at figures unseen since August 22nd. At Bitstamp, bitcoin’s value dropped to $4001.9 during the fall while a global average between exchanges leveled around the $4,050 figure.

Chinese exchanges experienced more dramatic falls with trading on ‘big three’ exchange OKCoin falling to a low of CNY22,550, roughly $3,400.
