Euro vs Lev - Bulgarian economy in June 2025

Bulgaria, June 2025.

Below are screenshots of ADs showed in my Facebook feed:

We are European Union members since 2007,

Also NATO alliance member since 2004,

With currency board, from 1997, connected witth exchange rate to the Euro.

People lost trust in the authorities and possessed lots of cash money. 

Where those levs should be invested or stored? 

Bank deposits, real property, financial assets, other goods, or gold?
