Polymath is naturally programmed to be a high hype product: as it is supposed to be the first blockchain project related to finance + assets industries. Not to mention possible big partnerships POLY might secure in the future.
As for the speculation: this can be a perfect coin. But just imagine if price goes 2x 5x / 10x even, the question will be: CAN THEY DELIVER?
Short term, I like this coin. But longer term: I m not sure how this will evolve.
