The type of investment doesn't really matter when it comes to having all your money into something. It's bad all the way.
Using 10% of your money for investment purposes may seem to be a lot for you, but in reality it's not. I personally always work with a 50/50 ratio. 50% investments, and the other 50% is savings in fiat. Right now my ratio is like 60% Bitcoin and 40% fiat savings, but that's mainly due to the fact that Bitcoin has increased quite a bit in value in the last 12 months.
