I am new to bitcoin and blockchain, I browed the website just now. There is a question confusing me, I find that one miner dig out blocks many times even in one hour. For example, this miner dig out four block in 6:00 - 7:00 AM. Is it possible that this miner control 51% CPU? And may this would break the whole bitcoin blockchain?
I hope someone can answer me, thanks!

Does this mean that two people B and D give some btc to E and F simultaneously? or there is one man B or D to initiate this transaction. Thank you again!1This transaction, there are many input, and takes the change of 124.98. Is it possible to use fewer input and less change?for example reduce 9 input and the change is less than 12.5 btc. – Issem – 2019-11-13T03:02:03.030
