that's right, it's not equivalent. @geohot called it "bridged bitcoin" but "burnt bitcoin" is more accurate.
*for now*, value would be at most 1BTC (bc u can always turn 1btc into 1bbtc) but with no lower bound... bbtc could trade at $0, pure loss.
only way bbtc can be > btc is if/when the btc chain dies.
