Fungible→ something replaceable/exchangeable.<ul><li>Currencies & goods are fungible because they are interchangeable with items of the same value.</li><li>Ex: exchanging one 5$ bill with five 1$ bills because both have the same value.</li></ul>Non-fungible→ something unique & irreplaceable.<ul><li>Items of sentimental/historical/unique value.</li></ul>

Fungibility (no it has nothing to do with fungi 🍄)

NFTs are at least partially responsible for the millions of tons of carbon dioxide emissions generated by the cryptocurrencies used to buy & sell them.Cryptocurrencies are built on a system called “<a href="https://www.investopedia.com/terms/p/proof-work.asp">proof of work</a>” to oversee transactions.The system forces "miners" to solve complex puzzles for a reward.The process is incredibly energy inefficient on purpose, making the "miners" use up inordinate amounts of electricity (that they have to pay, for making it less profitable for them to mess up).

Are NFTs bad for the environment?

They use the same <a href="https://www.thebalancesmb.com/blockchain-explained-4773366">blockchain</a> technology that most <a href="https://blockgeeks.com/guides/what-is-cryptocurrency/">cryptocurrencies</a> use.Most NFTs are part of the Ethereum (a cryptocurrency) blockchain but other blockchains can implement their own versions of NFTs.

How do NFTs work?

NFT stands for Non-fungible token. <ul><li>cannot be exchanged/replicated/replaced because they are unique.</li><li>allows you to buy & sell ownership of unique digital assets.</li></ul>

What is an NFT?

The creator just gets a shit ton of money and still gets to enjoy copyrights of their work so..... Win-win situation 😉.

Selling NFTS

NFTs are designed to give you something that can’t be copied: ownership (though a creator can still retain <a href="https://smartcopying.edu.au/guidelines/copyright-basics/what-is-copyright/#:~:text=A%20simple%20definition%20of%20copyright,how%20their%20material%20is%20used.&text=Copyright%20is%20a%20separate%20right%20to%20the%20property%20right%20in%20an%20object.">copyright</a>).Much like how physical art collecting is seen as a value-holding investment, now so are NFTs. However, instead of receiving an oil painting on canvas 🖼️ to hang on your wall, you get a JPG/MP3/GIF/etc file 🤷🏾‍♀️.

Wtf?!

Selling NFTs could be like selling a van Gogh painting, except instead of getting to appreciate a physical copy of something, you get a trading card. People will still be able to access & distribute the asset that you bought but you own it (without any copyrights though). So basically, you get bragging rights.
