Yes, it happens sometimes.
If you notice, that miner "found" that block within a few seconds after the prior.
So the miner did not add any transactions since it was so fast.

That 1 transaction is called the coinbase, which is where newly mined bitcoins come from.

It's not anything strange and It happened before with other blocks [1][2][3 you would've found the answer If you searched a little bit too http://bitcoin.stackexchange.com/questions/24098/why-there-are-blocks-with-single-transaction-in-blockchain

so the miner [F2Pool] is keeping the 12.5B for himself?

Miner [F2Pool] is a mining pool. Everybody that mines with them gets a share of the 12.5B.

What 1 transaction means is that they only get the transaction fees of that transaction on top of the 12.5B. This is obviously less than including say 1000 transactions, but some say it is tiny bit fast to not include transactions, thus generating more blocks for them.

No, the coinbase never has a transaction fee since it is self-mined and not necessary.
Transaction #2 and beyond are all bitcoin user transactions that may or may not have miner fees associated.

Exactly right. Finding a block is about luck not skill. Hashing a block with 1 transaction takes exactly the same amount of effort as hashing a block with 10,000 transactions. Creating an SHA-256 hash with a value less than the current target solves a block. It's possible to be extremely lucky and find a block a minute for ten minutes. Bitcoin has a measure called "difficulty" that will auto correct the amount of blocks found to one every ten minutes and difficulty is adjusted every 2016 blocks. But that doesn't mean it will be exactly one block per ten minutes because miners are "searching" for a random number. The difficulty adjusts so one block is found "on average" every 10 minutes but it's a race to find a random number. Some are found closer together (two in three minutes) and some are found further apart (one in twenty minutes). When two are found close together one will have fewer transactions included.

thanks... F2Pool is using the wallet address >> 1KFHE7w8BhaENAswwryaoccDb6qcT6DbYY for their new generated tokens.
https://blockchain.info/address/1KFHE7w8BhaENAswwryaoccDb6qcT6DbYY

Have they really generated a total of about new 810,000 coins?? If so - this is so much!!! too much I would say!!! this is not a decentralized system, isn't it?

when you see empty blocks, you usually see that they are solved quicker than average, this is both the cause and effect.

the reason. is simple.

say miner X solved a block... all the competitors
wait the few seconds to get the data
wait the few seconds to validate X
wait a few seconds to build up a list of transactions in the mempool that remain unconfirmed because if X proves valid they cannot include X's transactions in the next block obviously.

however by not including any transactions. pool Y can immediately start hashing a new block while it validates X separately, at the same time. and if X proves valid it can then start building a list of unconfirmed transactions to add to the Y pools attempt. giving them a headstart. and if it took them 10 minutes to solve a block they would usually have added tx's into a block and no one would know any difference.

you sometimes notice the more time that passes the more transactions appear in their block. but usually if the block is solved under 2 minutes, its usually empty

afterall its stupid to start hashing a new block full of transactions before validating the previous. but smart to start empty then add unconfirms as soon as you validate

They are also storing other bitcoin there, check few more transaction that are not only newly generated coins. They have received around 810,000 bitcoins in total which is quite normal for a big mining pool.

https://blockchain.info/pools
F2pool currently own 18.1% of total mining hashrate, so it is not surprising that they have generated a lot of bitcoins.
