I don’t think in percentage wise much when it comes to investment. You can keep investing as long as you keep having a good sleep. Of course, sometimes you won’t be able to avoid the stress. We are humans and humans have emotions. On the other hand, if you didn’t invest at all, you would have stress anyway for missing the opportunities. It’s ok to be emotional, it’s impossible to avoid it. I definitely believe in my investments, especially knowing tha fiat will cause huge inflation in the next few years or a bit longer. What helped me a lot when it comes to crypto investments was that I started with very small amounts, just for the feeling to be involved. Than the lower crypto dipped my investments increased. Last dip we had was my biggest amount I invested in crypto. This worked for me very well. Just don’t overinvest yoursel.
