The important thing when planning your asset diversification is to think outside your home country and not store all of your wealth in the same place.
Always be ready for sudden changes and shocks and divide your money in entirely uncorrelated assets: have cash in lots of different currencies, hold some precious metals, cryptocurrency or stocks while choosing markets that are not co-dependent.
Also, investing in real estate around the world could be a good way to get second residencies or even citizenships, so always consider all possible options.
