You think #bitcoin is not the future?
I suggest to allocate 200 eur now and make an experiment. Buy 100 eur worth of #bitcoin and store it in a private wallet (you control the wallet, keys). Other 100 eur put under the mattress.
See what you can buy with both in 4 years.
Saddly in 4 years you will figure it out you should have taken the time and studied bitcoin in 2023 or earlier.
You can start now.
