Out of curiosity I dug into how NFT's actually reference the media you're "buying" and my eyebrows are now orbiting the moon
Short version:
The NFT token you bought either points to a URL on the internet, or an IPFS hash. In most circumstances it references an IPFS gateway on the internet run by the startup you bought the NFT from.
Oh, and that URL is not the media. That URL is a JSON metadata file
Here's an example. This artwork is by Beeple and sold via Nifty:
https://t.co/TlJKH8kAew
The NFT token is for this JSON file hosted directly on Nifty's servers:
https://t.co/GQUaCnObvX
THAT file refers to the actual media you just "bought". Which in this case is hosted via a @cloudinary CDN, served by Nifty's servers again.
So if Nifty goes bust, your token is now worthless. It refers to nothing. This can't be changed.
"But you said some use IPFS!"
Let's look at the $65m Beeple, sold by Christies. Fancy.
https://t.co/1G9nCAdetk
That NFT token refers directly to an IPFS hash (https://t.co/QUdtdgtssH). We can take that IPFS hash and fetch the JSON metadata using a public gateway:

"Blockchain technology is energy-intensive..." => No, it doesn't have to be.
Let's look at Proof-Of-Stake, an alternative to the energy-intensive Proof-Of-Work algorithm.
🧵🔽
1️⃣ A Quick Recap On Proof-Of-Work
A Proof-Of-Work algorithm requires miners to do a certain amount of work that is compute-intensive to gain access to a service or the right to do something. This algorithm, by design, also requires that the work done shall not ...
... be reusable for anything else than what it was performed for. This lies at the core of the security concept of a blockchain. To gain the right to append a new block to a chain and to get some currency as a reward, there is work to be done, and this work must be verifyable.
That work is a race between different miners. Many miners try to compete and to be the first to find the answer to a problem presented to them. This implies that a lot of energy is wasted as only the first correct solution is accepted.

Let's take a higher-level look at how this one works, shall we?
\U0001f9f5\U0001f53d
I'm sure someone else has explained this, but it is just so cool and I want to explain how this works.
So Curve is awesome for swaps between similar assets, right? The fact that they trade very close to each other is a key part about how Curve works, using it's custom swap invariant function.
That's step 1
Step 2 is that Synthetix is awesome for creating "synthetic assets" (aka synths) which are assets that trade like other assets, that are backed by another, entirely different asset. Basically, a plastic banana that I can buy and sell like a real banana.
Synthetix has a feature that lets you swap between any two synths with zero slippage and a flat fee. That's because it is simply converting the sythentic asset into another synthetic asset, the backing for the synth doesn't change it just uses a different price oracle now.
This is important. Absolutely no slippage, at any size
Swap $1m sUSD for $1m sBTC? flat 0.3% fee
Swap $10m sUSD for $10m sBTC? flat 0.3% fee
swap $100m sUSD for $100m sBTC? Well, there isn't that many synths in Curve, yet but you get the point. The only limit is the pool depth

1/ Bitcoin: a bold new world.
Satoshi published the white paper on 10/31/2008. Right at the moment of peak despair during the 2008 financial crisis. Trust had been lost in a world that ran on trust.
2/ But why October 31st? It certainly wasn’t because Satoshi was a fan of halloween, it must have had a deeper meaning. With all of his actions, he demonstrated a careful precision.
He had been working on Bitcoin for at least a year and a half before publishing the white paper.
3/ “I believe I've worked through all those little details over the last year and a half while coding it, and there were a lot of them. The functional details are not covered in the paper, but the sourcecode is coming soon” - Satoshi Nakamoto
4/ On August 18, 2008 Satoshi registers registers https://t.co/rMWwiEwtxT through https://t.co/Uj8lMr10kB.
Satoshi was ready and waiting to hit the send button throughout 2008. What was so special about October 31st?
5/ I believe that Satoshi published the Bitcoin white paper on 10/31 as a hat tip to the ancient Gaelic festival of “Samhain” which was also the date in which Martin Luther nailed his 95 Theses to a church door. Both represent an end of the old and the beginning of the new.

1/ [December Bitcoin yield update]
Over the last year and a half, I’ve earned ~1.2BTC with various yield generating services to earn an average of 5% on 30 BTC.
Here’s my journey and how to guide👇
2/ Here are the ways you can earn yield:
Lending (Easiest/most popular)
Yield: 3-6%
- Ledn: https://t.co/4x0YATuQ0v
- BlockFi: https://t.co/90Xtg2cNka
Covered calls (Harder)
Yield: 1-80%
- Deribit: https://t.co/2iQVkXlylP
- LedgerX:
3/ Earning a yield enables you to stack more sats (what I’m doing), or reduce the temptation to sell your coin through earning an income.
The yield you earn comes with RISK!
Below is my current allocation for Dec (will update MoM)
(yellow = changes)
https://t.co/PZwVYs8lFT
4a/ [Nov > Dec Changelog]
- Covered calls: approx. 4 BTC was in $40k 12/28/20 contracts. Those closed without them being exercised (a good outcome for me). However, I was nervous about my January 1/28 $50k contract so I decided to close out my position at a small loss.
4b/ [Nov > Dec Changelog]
- In process of reallocating the 5 BTC (probably will be a lending platform).
- I incorrectly had my Ledn rate at 6.5%, it's 6.25%
