€120k at 27 yo coasting into a 0% CGT country. Is my coast number sane?

Self employed, based in the EU, moving to Bulgaria within the next year or so. Everything I have sits in one plain taxable account at IBKR, no wrapper anywhere. Long post, the real question is the coast number near the bottom but the tax setup feeds into it so bear with me. Income: €1,500-2,000/mo when the work shows up, zero when it doesn't. Self employed so that line is the shakiest thing here by a mile. Portfolio (all taxable, IBKR): ~€85k VWCE (FTSE All-World, accumulating), bought on Xetra
