Right now, many US stocks are overvalued and are at high risk for a correction within the next few years. Using historical averages for the last 20 years, the CAPE ratio for the US market is projecting returns to be only -3% to +3% for the next decade. Interest rates at are an all time low though, which may push expected returns up a bit from those numbers, but interest rates probably won't stay low forever. US index funds are a risky play right now.

Not all stocks are overvalued though. Look into buying value stocks that pay large dividends. Unsexy REITs, tobacco, bank stocks might be worth looking into again, as well as international or emerging market ETFs.

Bitcoin looks over-sold right now, but gold is relatively cheap as a hedge against inflation. The Fed pumping huge amounts of money into the economy will eventually lead to inflation. It might take a while though, since people need to be able to spend that money for inflation to happen. Various lock downs around the world are preventing this from happening, currently. If you're patient, I think gold and other commodities (Uranium possibly) are going to do well over the next few years. I think there are a lot of people buying Bitcoin as speculation and as soon as you have numbers go red, there might be a mass sell-off and switch to gold. The last Bitcoin halving event was just this past May which usually leads to surge in price as mining becomes more affordable, but as with other cycles, miners may start selling (since you can't yet pay bills with it) and prices will go down again until the next halving cycle.

To put things into perspective though: Aside from owning property, I'm about 5% REIT, 5% Gold, 20% Canadian index ETF (Canadian here), 30% international index ETFs, 10% US value stocks, 20% bonds, 10% cash.
