People may not use ETH for anything like Silk Road but the fact is that when BTC drops, ETH drops right along with it (ETH takes a harder hit that BTC in terms of percentage drop).
It's happening again, ETH is dropping really quickly at $239 just now (Saturday morning). By tomorrow morning it'll be at an all week low and it'll rise sharply from Monday through Thursday. Watch and see. I'm gonna buy $17,000 worth of ETH if it hits as low $219 and sell it again when it does $320 mid-week. That'll be almost $8k profit. Let's see if it happens.
