Straight answers
Is this an NFT or an investment?
No. You are buying a licence on this site, not a token and not a return.
The listed price is what we last collected for that address. It is not a promise it will go up, get traffic, or make you money. If someone takes it, they pay us — not you.
There is no token and no marketplace that pays the last keeper.
If someone sells you an address as an investment, they are talking about a different product.
