Jan 22 (Reuters) - Crypto custody firm BitGo ( BTGO ) was valued at about $2.59 billion after its shares opened 24.6% higher in their New ‌York Stock Exchange debut on Thursday.    The stock ​opened at $22.43 a share, compared with ‍the $18 offer price.    BitGo ( BTGO ) ⁠and some ⁠of its backers sold 11.8 million shares above ‌the marketed range ​of $15 and $17 to raise $212.8 million.    The listing comes as the ⁠crypto IPO window ‍tentatively ​reopens following tepid activity after the historic U.S. government shutdown late last ‍year. No major crypto-linked issuer went public in the U.S. in the fourth quarter.    Stablecoin issuer Circle, CoinDesk-owner Bullish, blockchain lender Figure, ​and ‍Winklevoss twins' crypto exchange Gemini went public in New York between ​June to September.    The debut marks the first major test of investor appetite for digital asset companies in 2026 and could influence whether other crypto firms ​move ahead with listing plans.
