It seems as though it's a good idea to start moving away from centralised services.
The biggest and boldest idea is to stop using central bank issued money such as US dollars or Australian dollars. Opt out and use Bitcoin instead. Start converting any left over money you have into bitcoin. Better yet, start earning it. Ask to be paid in bitcoin for the work you do. Offer a discount to anyone willing to pay you in bitcoin.
Since coming on to the Bitcoin standard, I don't particularly have a stock or real estate portfolio. I don't need one. I own money that is finite in supply. That does and continues to do all the talking for me.
Just to be clear, holding bitcoin defends you from parasites entering into your affairs.
