Stock market, bonds and real estate are popular choices to diversify out of crypto. You'll be looking to find sectors and assets that does not mirror the trajectory of the assets you currently hold.

Being a Bitcoin inclined forum, most of the investment advice here is around crypto. You'll want to find other sources to learn more about these assets and make your decision based on what you learn.

I also advice people invest in themselves by learning a skill with a good ROI and which won't be easily replaced by technology.
