The silent enemy of your savings
Keeping money "safe" in a current account isn't as safe as it seems. With average inflation of 3% a year, idle money loses roughly half its purchasing power in a little over two decades. It's not that you have fewer euros: it's that each euro buys less.
This doesn't mean you should invest everything riskily. It means understanding that the risk of doing nothing also exists, and that an interest-bearing account or a low-risk product that at least matches inflation is the difference between preserving your purchasing power and watching it erode every year.
