Nexo Platinum still worth it in Eurozone? Certainly not outside it!

I've been using the card daily, credit mode, quite confidently in the EU, Euro or not, but today I bought something big and DKK->USD was a whopping 3% currency fee (give or take). That's my 2% cashback burned before even the repayment process starts. In addition, whatever has been happening to interest rates where I seem to have lost 45% of my weekly earnings over similar activity between early 2025 and 2026, can you actually be left with a 0.something% real cashback in the Eurozone, or is the product close to dead as an investment and only alive as as convenience? Certainly an expensive way to acquire NEXO!
