I've checked the info on Coinamrektcap and Acala is pretty good and ranks at 333, the marketcap is also big and this really makes me believe that Acala in the future will be able to support Polkadot's finances.
Every transaction from Acal definitely requires GAS from Polkadot coins, unconsciously also that Polkadot is bought directly by Acala coin users and this is called financial support from Polkadot coins.
