Perfect portfolio?

After messing around with stocks for a time i came to a conclusion that the way of investing for me is ETF and chill. This gives more serenity and takes less of my time away making investement thesis and or managing the stocks i was holding. My new plan is savings plan at TR of 400 euro into the $VWCE (-0,23 %) & invest my leftover cash of the month into my savings account and $BTC (-0,02 %) . What do you guys think?
