alot of people wanted to get their UTXO in block 840,000 so paid stupid fee's to outbid competition, not everyone could get in so some are getting their tx added in later blocks so expect the fee's to be high, out of stupid milestone notoriety hopes
we will see this wave of idiocy of 840k notoriety bidding war die down and then go back to the idiocy of the newest junk/scam spam of runes that replaced the brc ordinals scam spam
What madness if that is really the reason.
many mining pools in favour of the spam/scam are part of the funding of it.
EG if a mining pool can get a utxo pertaining to be part of 'rare block 840k' and costing 40btc to create reward. then they can resell portions of that reward utxo for higher amount to continue the scam
its like many things
if you can fake that Xyear minted 50pence UK coin is worth £500 and you manage to sell 2000 coins for £500each but actual cost is £0.50each
then you can have a money pot of £1m scammed money to then go acquire 2024 minted first batch 50pence pieces and get 2,000,000 new mint coins which you can then try to sell each for £5000+ pretending it cost you even more thus have higher pretend cost. due to rarity and other sill notions
in short if reward block840k is worth 37btc then they can pretend rarest sat in transactions of block 840k is worth alot more so they can continue scam of their utxo spends to be worth more. pretending it cost them alot to get into block 840k
..
but its all nonsense gesturing and scamming, so dont buy into it. let them bankrupt themselves
