In which currency can I invest?

Investments are in Bulgarian Levas (BGN). Klear issues loans to Bulgarian citizens in the domestic currency.

The Bulgarian Lev is pegged to the Euro since 2001 and its exchange rate (1.9558 BGN for 1 EUR) has not changed since.

Although it is very unlikely that this currency board breaks, you should be aware that in such case your investments will stay in BGN and would therefore have a floating value in EUR.
