YouTube Copyright Strikes....But on different channels

Ok, so I've got 3 youtube channels going.

Channel 1: 0 Strikes
Channel 2: 1 Strike
Channel 3: 1 strike

What I wanted to ask if I get one more copyright strike on any channel will all my channels be shut down or does it have to be 3 copyright strike on only ONE channel in particular.

90% of my money made on YouTube is the one that has no copyright strikes so I would just take down the other channels if it 3 strikes on any channels to stop any more potentially coming down the line.

One channel get 3 strikes, not total channels.

Yeah right its 3 strikes to a specific channel and that will close that specific channel and not the adsense and other accounts linked to it.
But make sure if your primary channel gets banned then you will lose access to youtube and other channels will not be in your control.
