Cryptsy, a popular exchange for buying and selling bitcoins, announced the bounty in a blog post on Thursday, which also attempts to explain the company's numerous recent service interruptions: Cryptsy alleges it was hacked in 2014 and lost millions. Now, they want it all back, and they're willing to pay. The post also states that the exchange is suspending all trading "indefinitely."

At the time of writing, Cryptsy's website appears to be offline. (Update: the site came back online just before 3 PM EST.)

The company didn't tell anybody about the hack in 2014, according to the blog post, apparently figuring that since they were making money at the time, and had reserves of currency they could lean on to keep the exchange afloat, everything was just fine.
