That's a great point. I mine ETH primarily (because it's most profitable for my hardware) and trade it to get in on all kinds of things, but I was fortunate enough to get 2 RX570s before the price went up. BURST mining is more of a "well, this PC is working anyway" type of currency, but I also really like what they are doing with it. Having the ability to reinvest through the marketplace, etc adds an interesting option.
