Herewith I present my portfolio again. I am of course open to suggestions for improvement!

Briefly about me: I am 21 years old, still live with my parents and work as a system administrator.

I'm currently looking for a new car, so €20,000 of the €22,500 cash will probably disappear.

Due to the fact that I still live with my parents, my savings rate is around €1500. By saving for the new car, the savings installment that will be invested amounts to "only" €500.

350 per month currently goes into the savings plan $IWDA (+0,37%) and 150€ into the $AE5A (-0,86%)

In addition, "another" €60 goes into the building society savings contract, and €70 goes into the Riester pension on the $UIVD (-1,47%) I also have a BAV, here the savings rate is €40.

Now I had the following idea: Close the building society savings contract and invest in $BTC (+0,25%) and invest in the World ETF? What do you think of this suggestion?

I'm also currently undecided about what to do with the smaller positions >€500.

Thanks for reading and have a nice evening! :)
