What is amp coinbase quiz?

As an AI language model, I do not have access to any specific information about the quiz hosted by Coinbase on Ampcoin. However, since Ampcoin is a cryptocurrency that is tradable on Coinbase, it is likely that the quiz was about Ampcoin's history, use cases, and technical details. The quiz could also have covered trading strategies and market analysis relevant to Ampcoin's performance on Coinbase. Participants of the quiz may have been rewarded with Ampcoins or other incentives, depending on the rules and regulations set by Coinbase.
