Recently I sent some polygon mastic coins to my HW wallet (ledger) and after receiving the coins in Ledger Live, I also noticed that there have been received two NFTs Airdrop at 5000usdt.us and 5ETH at geteth.us.

I clicked on one of them and there was a button View in explorer I clicked on, which opened web browser, but the page didn’t appeared, just a blank page.

I searched for and found that such NFTs are scam and shouldn’t be interacted with.

What I would like to know:

• is there a risk that scammer can steal my mastic coins just because I clicked on view in explorer?
• is there generally risk after clicking on that button, that another wallets would get affected and emptied by scammers?
• can be seed stolen if it has never been entered online, e.g. when ledger is connected to the PC?

My questions might be stupid, but I am new to cryptocurrency activities and having a HW wallet.

Btw, I keep my seed in my memory, there isn’t any paper I wrote it down. I keep it in my head.

Many thanks in advance.
