@OP I don't think the transaction fees will be cheap in very soon because there's no implementation yet to stop BRC-20 or maybe it's impossible to stop. I think the current fee will become a new normal, just like Ethereum network.
Or ask your favorite casino to accept deposits/withdrawals through the Lightning Network. I believe it's not just the best time to start asking, it has now become absolutely very necessary as a Bitcoin-only user.
Usually a casino is really slow to updating a new development, this because they're either focus to other sectors e.g. promotion, gambling provider etc. I can't remember which casino have adopt lightning network from someone in recommend it in this forum, I only know the casino was already accept lightning network from the beginning.
