So, I was checking out the mempool graph and saw a bunch of transactions in squares of the same size. Then I noticed the same pattern the next day. I decided to check out these addresses and man, they are cranking out a ton of transactions to their own accounts every minute, and the fees are super tiny.
Here are the addresses I found:

What could they possibly be up to?
This is a pattern but it is unlikely to be a spam for profits because the fees are ridiculously low and nether is it an attack.
It is looking like an automated bitcoin activity, generated by software because humans can't send repeated identical transactions per minute with the same structure, almost identical size and timing.
I showed this to my friend, he was of the opinion that someone is washing bitcoin in a traditional way. But I didn't actually understand his explanation because they are sending to their own addresses.
If the goal were obfuscation, you will expect coins to move across many unrelated addresses.
Sending coins back to oneself is commonly about UTXO management, fee optimization or for testing automated systems.
Seems unlikely to be UTXO clean up because the transactions are very small.
They did transfer to another account at some point, I've seen these accounts have above $20k at least at some point, now some are empty.
For laundering seems silly, since there are AI tools now that can follow the money pretty easily.
That's an ordinal inscription; it looks like an NFT in the ERC20 or Binance/Ethereum network.
It's a collectible thing behind the Bitcoin network.
You can buy them or sell them on MagicEden, and based on Coingecko they only have a Discord community.

This is the overview for the first address. You can see that they have made over half a million transactions and a lot of that activity is related to inscriptions. Those inscriptions are just data added to transactions to represent tokens on the Bitcoin blockchain.
These inscriptions are useless but unfortunately many people lost money and bitcoins to these inscriptions and those projects. They should hold their bitcoins rather than selling/ converting their bitcoins to such useless inscriptions.
Phobos_Quake can understand more about this with these reports from Glassnode Insights.
Ordinal theory and the rise of inscriptions.
Inscriptions, Mempools and Miners.
It means someone succeeded in making gullible people believe they buy something of value, while in reality they buy just Bitcoin dust. It's one of many similar schemes we've seen since Bitcoin was created, and most of them die off a few years later: altcoins, ICOs, Forkcoins, NFTs, Ordinals, Runestones, and I probably forgot a few already. It's not the first, and it won't be the last.
