What is DOP in buying?

Excuse me, could you please clarify what you mean by "DOP in buying"? In the world of cryptocurrency and finance, the term "DOP" isn't a widely recognized acronym that I'm immediately familiar with in the context of purchasing or investing. Could it be a specific platform, token, or service that you're referring to? If you could provide a bit more context or explain the context in which you encountered this term, I might be able to offer a more accurate explanation. Alternatively, it could be a typo or a regional term that I'm not aware of. Clarifying your question would greatly help me in providing a relevant and accurate response.
