Something is brewing in the Bitcoin world? For the last 2-3 days I can I witness slow transactions and huge fees. I got used to 1sat/byte transactions and they always get through so I sent a couple of sats to myself but you can't imagine how surprised I was when I saw my tx is ~75mb from tip! My wallet suggested a fee of 10sat/bytes! So, what's going on? Is this connected with that ordinals mumbo-jumbo?

Take a look até
http://mempool.space/ to get the fee rate you need to use, this is the best site available for that.
Now you need 22 sat/vbyte for a confirmation, which is not huge.
The reason is an app called Ordinals, something like an NFT using bitcoin.
The introduction of the Ordinals Protocol, which enables the development of Bitcoin-based NFTs, has coincided with significant changes to mempool activity and transaction size, new data by CryptoSlate and Glassnode show.
