Ops of the day:
Bitmain lost $150,000 because it mined an invalid Bitcoin block
Bitmain lost $150,000 because it mined an invalid Bitcoin block
Bitmain-owned mining pool Antpool appears to have squandered at least $150,000 worth of Bitcoin mining rewards, reports BitMEX Research, the analytic arm of cryptocurrency exchange BitMEX. … (link:

According to BitMEX Research, the Bitcoin network denied Antpool’s block as it featured an erroneous coinbase transaction.
Instead of 12.5 BTC, whoever mined the block seems to have requested a reward of 13.26 BTC ($154,700). This appears to equal the correct coinbase transaction (12.5 BTC) plus the sum of the associated transaction fees.
“The coinbase value was too high, presumably because this included the transaction fees, but due to some error the transactions themselves were not included,” tweeted BitMEX Research.
Well, this is an invalid block, so a block that was rejected by bitcoin nodes and then not appearing on the blockchain. That's a different mishap than mining a VALID block, but forgetting to claim the coinbase!
I cannot find that story, can someone help me I recall a list of all "lost bitcoins" that prevent getting to theoretical limit of 21 millions.

Can anyone guess what happened?
What is the point of mining empty blocks?
What's the difference between SPV and selfish mining?
EDIT:
I found the thread about lost bitcoins!
https://bitcoin.stackexchange.com/questions/38994/will-there-be-21-million-bitcoins-eventually/38998#38998Not really relevant here, but fun read!
EDIT2: Added some more infos on the lost block from my node.
