March 3 (Reuters) - Silvergate Capital Corp said on Friday it made a "risk-based decision" to discontinue the Silvergate Exchange Network, after the crypto-focused bank raised going concern doubts earlier this week.

"Effective immediately Silvergate Bank has made a risk-based decision to discontinue the Silvergate Exchange Network (SEN). All other deposit-related services remain operational," read the notice on Silvergate's website.
