First is to stop unnecessary spending of your money so that you can store and retain the value of your money. Prioritize what are the things that you have to purchase and stop eating outside. Well, for some cases in some other locals and countries, they're telling that it's cheaper to eat outside from those convenience stores like eating with bentos and buying that meal for one that costs them lesser than cooking their own food.

The things that OP mentioned are good investment vehicles to store your wealth to fight inflation. You have to remember that those assets where you'll be putting your money should generate more profit in percentage of the year's inflation. Obviously, if the inflation for this year is about 4% then you should get about 4.5% or even more from where you'd put it. And with Bitcoin, it's outperforming those percentages when it's getting to the bull run.
