The Tax Authority still treats crypto and NFTs pretty ambiguously, but what really matters is whether they consider your activity as occasional investment or habitual commercial activity. If you sold a few NFTs and cryptos here and there, you're probably looking at capital gains (subject to tax, of course), but if you're constantly buying and selling, they'll want to treat it as professional income, which completely changes your tax classification.
What's your situation - were these a couple of isolated transactions, or are you doing this regularly? It also depends on whether you can demonstrate it was legitimate investment versus speculation. The safest bet would be to consult a tax accountant who really knows crypto, because it's an area where the Tax Authority is still playing catch-up and interpretations vary quite a bit.
