I'm going with polo-pump. We'll see....
Even if that is the reason, the high volume and price increase probably attracted a lot of new awareness.
I completely agree that all the XMR fundamentals are looking very good now. I just don't think those fundamentals were the things that attracted all this money to XMR recently. I think ETH brought massive money onto polo and XMR is benefiting from the bleedover. This happened during the 2013 BTC bubbles where bitcoin brought money onto BTC-E and then LTC and PPC went up towards the end of the bitcoin bubbles. I believe the same thing just happened on polo with ETH and the smaller coins on polo.
I also agree that this is great for awareness of XMR. Many people were drawn into BTC just for the pump, but then they learned about BTC and began to believe in the idea of an independent money. The same thing could happen with XMR. People may come for the pump, but then stay for the fungibility.
