What Makes One 'Virtual Token' more-valuable than The Other 'Virtual Token'?

Tweet

My cryptotab-browser (a browser with a crypto-miner attached) keeps 'pop-up ad'-vertising a slightly different browsing-miner---telling me to spend the few 'Bitcoins' I've mined to invest them in an NFT-miner instead. I look into it a little bit, but ... it's too 'high-flying' for me! I'll quote a little bit of it to show you what I mean---and maybe I can explain a little (and you can correct me when (not if) I'm wrong). "Our mining technology is based on the PoS algorithm which is superior to the CryptoTab Browser one and grows your BTC income more than just twice. NFT Mining provides you with an income in Bitcoins and a stable hashrate. Activate tokens and get long-term income in BTC, as any hardware will be enough!" Here's some background (stuff I think I know): The 'mining' they're talking-about is basically 'a program on my computer (like a similar program on lots of other computers) sending-in guesses at the number a main computer's thinking-of; when one of us "sends in a guess" that's right ("hashes" the right number) & that number is verified, the right "hash" earns a share of the "gas-fee" (the money paid by the user who's sending the cryptocurrency to another user). 'The "hashrate" is the number of guesses a miner sends-in per second. 'BTC is the abbreviation for Bitcoin. (Currently, 1 dollar buys 0.000050184 Bitcoin ... although I bet it's more impressive to say "$19819.87 buys 1 Bitcoin!")' So I guess NFT Mining is 'when somebody buys an NFT and they pay a premium gas-fee to transfer ownership of their NFT?'
