What chain will the miners choose to mine on when the lightning network is in full effect?

1. BTC which lightning transactions do not require any use of miners.
2. BCH currently capped at 32 mb.
3. BSV already successfully producing 128mb blocks with no scaling ceiling where as much data as possible is encouraged for use on the blockchain in support of the original protocol.

What happenens to miners and the billions of dollars already held up by mining producing companies and those heavily invested in the equipment already when on chain transactions are no longer the use of payment (lightning network)?
