There is lots of great advice here. I don’t want to cause contraversy, but I would suggest to invest between 10-20% of the investment money into high risk assets such as cryptocurrencies.
I have most of my investments in different funds (tech, medicine), a bit in a savings account (for emergencies) and a bit in crypto. I know there I a lot of hate there, but they have proven that they are here to stay. There is lots of fluctuations that can be hard on the nerves, but in the end, even though this is where I put 20%, it is today worth more than the rest combined.
