Plasma Mass Withdrawal vs Simple Withdrawal


In a byzantine situation, why should individual go through mass withdrawal rather than simple?

In a individual’s point of view, simple withdrawal seems to be fast and simple withdrawal is not banned in a byzantine situation too.

Then why should one choose mass withdrawal? I know fee can be relately low, but I can not think of other factors
than fee.


I actually don’t think mass withdrawals are necessary, especially in a plasma cash setup. Each user could just wait until either their account specifically gets attacked or they actually need to move their funds and only do a plasma withdrawal then.
