Sorry let me be more clear: There are a few big miners that don't use say, ocean, because they don't want direct custody of the #Bitcoin as part of the block subsidy because of the tax implications. They WANT FPPS because they can sell it immediately when taking custody from the pool and not have the 100 block delay. Their compliance, doesn't allow that gap. They can then go back later and buy #BTC with any profits, instead of mining directly. Which is stupid when you think about it.
