I still think Real Estate (properties but also including land assets) is the safest haven. It's the best hedge against inflation and economic collapse, as people still need a place to live and there is a finite supply of land available to build/inhabit in.
Crypto has a world of potential, but we might not yet be in that world. It could very well take a total collapse of the US Economic system (looking to have a high potential at this point) to set the stage for a decentralized form of currency that can connect the "unheard" masses and get the greedy hands of the central banks out of the finances of the average person and business.

Here's the downside:
-Real estate can be compulsorily acquired by the Government.
-It is not immovable and cannot be transferred across boarders.
-Huge friction in transaction costs (both to buy and sell).
-Maintenance costs ongoing.
-Requires ongoing effort if renting it to earn a yield.
-Can be heavily taxed (both on acquisition, on an ongoing basis, and massively via capital gains tax on any sale).
-For most people is leveraged, and value is thus highly influenced via interest rates. (This can be both a positive of a negative).
-Virtually unlimited supply can be produced in most countries, unless a very small place like HK or Singapore or Monaco (via more apartments that can be built upwards on plots of land).
