Thomasinu I haven't tried that since I never had a hardware wallet but I suggest that you send a ticket or better contact eToro's customer support via email or live chat to verify if they support native segwit addresses. Or, maybe try sending a small amount to the external wallet's address to see if it is supported or not. That's what I did when I wanted to check if my eToro wallet will successfully transfer the crypto to my Binance wallet (which it did). I suggest that you try sending the smallest amount that they allow. The interface will most likely indicate the minimum amount. Try transferring 0.00025 BTC (that's around $10) for a start.
