That's why we shouldn't made something decentralized become centralized because something like this would happen someday.
But, limit maximum withdraw to 70% or 90% is stupid. Sometimes people need their money quickly & don't have time to contact others

There's no limit on withdraw, you can get all your BTC back. The limit is on only debit transaction. Not on your BTC balance.
