In other words, it wasn't "unexpected," which was the notion pushed by the r/Unexpected subreddit on Reddit. Evolution of Mining You may have heard that Bitcoin transactions are irreversible, so why is it advised to await several confirmations?

Cudo Miner is simple enough for anyone to get started with, yet has features and benefits essential to Pro miners. It provides the highest profitability in the industry and it’s the only miner where you can actually earn the coin of your choice while mining the other more efficient coins, so you always get the most profitable solution. Why Mine Bitcoin? In order to win a block in most cryptocurrencies, Bitcoin included, a miner has to be the first to guess a hash value equal to or lower than the one that Bitcoin generates for the transaction. As more miners compete, and more computing power is deployed, each miner’s chance of coming in first is reduced—the current odds are one in the tens of trillions—helping ensure a pace for creating new blocks that is currently about one every 10 minutes.
