Crypto might play a big role in your portfolio’s growth if you bought your crypto assets during the market crashes or did DCA.

The percentage depends on your risk appetite. Some people go full crypto but I don’t recommend that route. I prefer to have a more traditional portfolio that mostly has stocks and bonds. Some cash and physical precious metals are also good to have.

In this day and age, if your portfolio doesn’t have any crypto assets, you are playing the game wrong imo.
