It's true that drivechaij pegouts take a long time (months). Some people have been saying that this is bad.

It's actually good since it ensures that a hostile majority would need to control hashrate for a long time in order to steal from drivechain users. Meanwhile, just like submarine swaps on Lightning, anyone would be able to instantly and trustlessly swap drivechain coins for mainchain coins so the slow withdrawl window would not affect users.

Pay attention to the people telling you the slow withdrawl is bad. They're either stupid or lying.
