What pirate said is pretty much what every other ponzi says when it collapses: funds tied up, you'll get them as money comes in. I seriously doubt people will be getting their money back. Expect more excuses about having trouble getting it back out of assets later this week.

Edit: If he had all the investors' bitcoins, which he said himself he doesn't, he could pay everyone back now...or start right now as opposed to waiting until Monday. He is only delaying...watch...
