Oh and FYI, guys are making MILLIONS selling their rare sats getting like 5000x what they are worth as a single sat and prices are going up. Again not NFT’s, all natural un molested sats. You could be holding some and not even know it (but you can check and isolate them).
How is one supposed to check their UTXOs for presence of rare sats?
1. Use explorer which support Ordinals or other NFT such as
https://ordiscan.com/2. Enter your Bitcoin address on search bar.
3. Click on tab or section which shows any rare sats.

The website also have statistic and price for such satoshi on
https://ordiscan.com/rare-sats, but i don't guarantee it's accuracy.
