To understand why, read up on transaction fees on the bitcoin.it wiki. Specifically, priority is defined by: [pre]  priority = sum(input\_value\_in\_base\_units \* input\_age)/size\_in\_bytes[/pre] The priority for the 0.1 BTC transaction is: (6 \* 10000000)/435 = 137931 The priority for the 1 BTC transaction is effectively 0, as the input\_age is 0 blocks. Therefore, the 0.1 BTC is processed first. It’s not a “random selection” by the miners. Don’t shed too many tears for the guy though, as he’s burned a lot already (since January 10th, actually) ---
