if you want 25 newly minted coins, and you're willing to pay a premium, why not just spend the coin renting enough hash power from somewhere like nicehash or MRR and point that power to ck.'s solo pool?
Because those solo pools' blocks are shared;
If you find a block, 99.5% of the 25BTC + transaction fees get generated directly at your bitcoin address!
That's why he'd probably have to actually
solo mine against his own node. Unless he wanted to pay a pool operator
BTC26
up front, trusting them completely (in lieu of an escrow service), and wait around until that pool finds the block with it paid out in full to his address of choice.
As it is, there's only a few services where you can
buy 'clean' coins; Hedgy's MBP contract and BlockTrail Mint, for example, but they're still intermediaries (e.g. BlockTrail's is Miner -> Mint -> You)
).
