If I understand correctly, your second transaction is from Blockchain.info, going to BTCC. As you said, the network propagation is very low, hence the mining pool might not have even seen your transaction. They may very well be prioritizing their customer's transaction but there is nothing they can do if majority of the nodes do not want to relay it and it won't reach their pool. Most nodes are refusing to relay your transaction as it can't be considered as a free transaction and has a fee below the network relay fee. What they can do is to offer a page for users to directly broadcast raw transactions to the pool.
-snip-the question is not about delays of relaying it to the mining pool's mempool.. its about how often the mining pool wins the blocksolving game before other pools in the world do.
which based on 13% hash power is only about one block an hour
i just grabbed the last 30 blocks from 385395 back to 385365
out of 30 blocks (5 hours) it should average 5 blocks solved..
. i count 4
block 385394
block 385388
block 385386
block 385377
so lets just realise that its not like BTCC will confirm your tx every 10 minutes guaranteed..
BTCC even though controls only a small portion of the hashrate, they have mined many blocks after OP broadcasted his transaction. Many of the blocks are not even half full, some even at 0.1MB which means that they can still mine OP transaction without difficulty and confirm it. Unless the service has not yet launched or the mining pool hasn't seen it, there is no reason that it is still unconfirmed.
