Eth is doing just fine on poloniex. From 0.50 to currently $8 with a high of $14
SLR is not ETH. SLR is purely for people who believe in renewable energy. Many speculators don't give a damn about renewable energy and just want to make a quick buck. So why would you want them to hold onto the SLRs? They don't understand the potential.
Sure SLR could get pumped and dumped but if you want to see Solar be promoted then you should buy SLR from Bittrex and hold it before the speculators with big money and no interest in SLR get a hold of it.
