The comparison to Madoff is not apt. Madoff hid losses by committing accounting fraud, whereas every single transaction in the Bitcoin network is visible to everyone and, moreover, cryptographically verifiable by everyone. As long as the distributed consensus algorithm continues to function, Bitcoin will continue to exist. Period. (Government regulations cannot kill it; they can only drive it underground, as with gold.)
Anyone who predicts Bitcoin's demise must explain precisely how and why its network would stop functioning.
