Hi, I’m quite new to solana/phantom:

why can I burn some tokens and some not (see 1st picture)?

Has it some something to do with the different networks they come from?

My second question is about the NFT in the second picture: I guess it’s a scam, because why should anyone give me 100 SOL ;-) But if it is a scam: then how would that work for them, as there is no link to a website or anything?? Don’t people have to pay for minting NFTs?

Also sometimes I get NFTs from Validators I staked in that don’t seem to be a scam, as they only contain a “funny” image. But what is the use or sense of these? Can I do anything usefull with it or is it the best to burn it in order to at least get the sol?
