San Diego's Silvergate Capital made its name in recent years as one of a few traditional banks providing deposit, fund transfer, security and other services for the cryptocurrency trading market.
But two-high profile crypto-exchange bankruptcies — one of which is alleged to involve fraud — have sent the small financial institution's shares reeling, and drawn the scrutiny of lawmakers.
Silvergate's stock price has plunged 88 percent from a 12-month peak of $162.87 last December, trading at $18.80 midday Tuesday on the New York Stock Exchange.
