This is the right course of action. Many tax authorities don't care about source of wealth, which you can use to your advantage. Declaring the funds and paying taxes increases their legitimacy.
Once that's done, you can try depositing the money in cash. Proving that they have been declared and taxed should help quite a bit with getting the money into a bank. However, there may come a point when banks question the funds even if taxed. It's especially unusual that it's a foreign currency. Bulgarian banks know that large piles of foreign currency means the money didn't come from anything local. Very few exceptions to that.
OTOH, 140,000 isn't a huge sum of money. Unless he's in a hurry to spend it all, your friend can simply use that money for day to day spending over the next couple of years while his normal income streams go directly into savings/investments.
If he really wants the money in a bank, a trip to Turkey might be in order. No limits on bringing in foreign cash and the banks are very happy to take foreign currency. Source of funds checks are very lenient in Turkey. Head down to Istanbul, get a local tax ID, and then go open personal bank accounts. Have seen it done just in the last couple of months.
