Bitcoin is coming out of the long weekend holding onto recent gains, keeping it elevated above the $20,000 mark for the first time since the collapse of crypto exchange FTX.

The world's largest cryptocurrency by market value was recently at $21,309, up 1% from its level 24 hours earlier, according to CoinDesk. It had tumbled after FTX faced a rush of withdrawals and filed for bankruptcy protection in November, then struggled to regain momentum in the weeks that followed as crypto traders turned skittish.

Based on 5 p.m. ET prices, Bitcoin is poised to advance for 14 consecutive days, its longest such streak since 2017, according to Dow Jones Market Data.

Crypto investors are hoping Bitcoin's recent gains could spell the start of recovery in digital-asset valuations, through bitcoin remains well off its record high when it was more than $60,000.

Ethereum was recently around $1,579, up 0.2% over the last 24 hours, according to CoinDesk.
