I don't think an offshore company gets around the requirement to report your holdings. You would legally need to report on that company and pay taxes on any profits if you are a US citizen. But you could likely defer taxes this way, by holding the bitcoin with the offshore company. You would then only pay taxes when you liquidated the bitcoin and paid yourself something. Whereas if you held the bitcoin yourself, you would need to liquidate to pay taxes every year that it increases in value.
