If you already have a 6-month emergency fund and are contributing to your employer’s retirement plan (if you have one), it's worth considering investing in crypto. But once again, since all cryptocurrencies are high-risk assets, you should only make them a small part of your investment portfolio.
Never invest any money you can’t afford to lose, or that would alter your life negatively in some way. You've invested way too much if you can’t sleep at night because you’re worried about your crypto holdings.
