Coinbase said in an updated tweet that buying and selling would likely not be available until Wednesday. Bitcoin cash trading has also been suspended on GDAX until noon on Wednesday.

The news sent the value of bitcoin cash soaring more than 50 percent to $3,800 per coin. It then retreated to $3,549 per coin as of 7:20 GMT.

The original bitcoin, which was trading at more than $19,000 on Tuesday, slid to $16,353 in less than 24 hours.

Bitcoin cash split off from bitcoin on August 1 after a group of developers decided to try to improve transaction speeds and costs. The majority of those who supported the conventional bitcoin failed to reach an agreement this fall on their own upgrade proposal – SegWit2x.

At first, the split did not impact the price of bitcoin. The newly minted bitcoin cash became worth around $600 per token. However, since August, the value of all bitcoin cash in circulation has soared from about $10 billion to $60 billion.

Bitcoin payment processor BitPay and major cryptocurrency storage company Blockchain recently said they would support bitcoin cash.

The community of bitcoin supporters have also split into rival camps, with some shifting to bitcoin cash.

The co-founder of Bitcoin.com, Emil Oldenburg, recently criticized the cryptocurrency as the “most risky investment you can make,” after he transferred his investment to bitcoin cash. He has encouraged investors to sell the “high risk” bitcoin, calling bitcoin cash “the future.”

“I’ve actually sold all my bitcoins recently and switched to bitcoin cash,” Oldenburg said. “As soon as people realise that this is how it works, [they] will start selling.”
