Now this is not clear what happen to next on bitcoin near future because bitcoins dominance is increasing and altcoin crashing.
It's pretty clear.BTC as it exists today will become the 'banker currency' as transactions are forced onto regulated custodial nodes on L2.
This will cause a backlash which will see the rise of altcoins that have the ability to handle scaling on-chain using non-custodial mining nodes the way Bitcoin was originally designed.
