The best place to put your money is typically where nobody else wants to put theirs. IMO nobody wants cash today. They want anything except cash no matter how risky. Stocks at highest valuations ever, BTC (unregulated), emerging market high yield, bonds with negative yields (because they think it will price appreciate), art, cars, volatility selling (fixed gains & unlimited losses), etc.

The least desired asset class right now is cash. Compare that to 2009-2011 or so & cash was the prized asset class which underperformed going forward. Aside from the least desired, the cheapest asset class in the world today is volatility.
