Ok where do I invest my money then?

Well-diversified mutual funds, or something equivalent to that, and in particular you want a mixture of asset classes such as stocks and bonds. You also want to have a hierarchy of investments, ranging from very low-risk but also low-growth investments for your emergency savings that you can tap at a moment’s notice to high-risk but also high-growth investments for savings that you do not need to tap for a long time (such as for retirement, assuming that is far off). “High-risk” in this context doesn’t mean “risk of your investment disappearing” so much as “risk of your investment suffering from a dip in value at the time when you need it”.

But to reiterate: the most important thing here is diversification, because diversification means that some of your investments can drop in value by a lot or even become worthless without causing you to lose everything. Putting all of your money into a single asset or kind of asset, such as a cryptocurrency, is basically the opposite of what you want to be doing.
