Coinapult, one of the longest-operating bitcoin start-ups, has gone through a hot wallet attack that led to the loss of 150 BTC, or approximately $42,900 at press time.



Founded by Ira Miller and investor Erik Voorhees in 2012, the company took to twitter for the announcement and cautioned users to refrain from sending bitcoin to its addresses until the problem is resolved.



However, Coinapult COO and CFO Justin Blincoe insisted that the hot wallet contained funds owned by the bitcoin wallet and service provider, and that funds owned by customers were not affected.



Blincoe told CoinDesk: "Our team is looking into all possible scenarios in regards to what happened."
