Bitcoin cash fell from its session highs on Wednesday, briefly trading back below $4,000, after Coinbase-owned GDAX restarted trading in the bitcoin offshoot.
The digital currency fell near $3,330 in afternoon trading following the news, but had recovered to $4,184 as of 5:22 p.m., ET, up about 45 percent over the last 24 hours, according to Coinbase. Bitcoin itself fell about 8 percent to $16,130, the website data showed.
Coinbase said late Wednesday afternoon ET that it was allowing bitcoin cash buys and sells, although the service was paused as of publication.
The company had originally halted bitcoin cash trading as it waited for "sufficient liquidity" to reach the cryptocurrency.
Trading in bitcoin cash launched Tuesday on GDAX at 7:20 p.m., ET, before being suspended after only four minutes as a lack of sellers caused high volatility. Many tweets showed Coinbase charts temporarily indicated bitcoin cash was trading well above $8,000.
Bitcoin cash was created on Aug. 1, when Hong Kong-based digital currency exchange Bitfinex said a group of bitcoin miners would be "forking" from the main bitcoin to create a new version that trades faster and more easily.
The new digital currency has had a staggering run higher ever since it split off, rising more than 780 percent in that time period.
