How much is 1 dyor?

I'm curious, could you please clarify for me the value of 1 DYOR? Is it a reference to a specific cryptocurrency, or perhaps a unit of measurement within the broader blockchain ecosystem? I'm familiar with many terms related to crypto and finance, but 'DYOR' isn't immediately recognizable to me. Is it a recent development, or am I simply missing something fundamental? Any insight you can provide would be greatly appreciated.
