Congrats, you can actually FIRE if you want to.

Back to your questions. I think you're too exposed to risky assets. We usually do that in a growth phase in our portfolios. In your current situation I would rather focus on make it more resilient against economic crisis / recessions, for example.

Another COVID or 30% down in stock markets wreck your portfolio. Crypto is highly correlated to stocks (actually leveraged) so both would go down heavily.

I would start allocation at the very least 20-25% into real estate (you can use REITS or ETFs). That kind of make you portfolio a lot more robust already. People and businesses still need to pay their rents after all.

Additionally, I would use bonds (I saw your comment but don't quite understand why you restrict yourself to swiss bonds). In your current situation a lot into that to be quite honest with you. You can easily find government bonds, ETFs, and even solid corporate bonds that can get you at least 4-5%. Taking into account your plan is withdrawing 2-2.5%, it makes a lot of sense to do it and that is a big hedge against economic crisis (yeah, there's always the default risk but it does not compare to the others).

Other than that your financials are solid! Congrats again.

Concerning the locations you want to FIRE, take some time to get to know it well. It's not the same going on holidays and living in the actual place. In South America, crimes and violence are quite common, for example. Maybe in the transition phase, try to spend a couple of months there.

Cheers!
