Bitcoin and other cryptocurrencies were rising on 26 January, bouncing back after a deep selloff that began late last week. There is optimism that the worst is over, but a looming decision on monetary policy from the Federal Reserve remains a risk.

Bitcoin, the leading digital asset, was up more than 4% over the last 24 hours to around $38,000, according to data from CoinDesk. It had traded hands near $33,000 in the depths of 24 January's selling, but topped $43,000 less than a week ago.
