Yes, you are correct. Our goal is to provide a service primarily for miners and mining pool operators, making it more convenient for them to sell their coins without the hassle of using multiple exchanges and incurring withdrawal fees. We don't anticipate a significant volume of Bitcoin being traded that would necessitate mandatory KYC requirements. - For now. What future holds if anything, we don't know.
If I understood you correctly, your service is to provide liquidity to OTCs to sell their Bitcoin holdings. If that is correct, then I think you have understood it wrong. These markets are highly regulated and subject to oversight, so KYC is not a priority.
If so, I do not think that a mining pool will sell you an amount of 1 Bitcoin, which represents an amount higher than the money laundering reward limits, which means that you are forced to ask users for their data.
Miners and mining pool operators sell for amounts of at least $50,000.
