Honestly there's no way to know for sure. I think it's got a lot of room to grow from where it's at, though. BTC kinda hit it's bottom and I doubt it'll go lower than ~5800. Eth will usually follow trends with BTC, so we're pretty close to where the bottom of the price is for now. If anything, I'd say now is a pretty good time to buy more, was the best time only 3-4 days ago when eth was around 400, but that may not come again. Who knows, you can wait but you risk missing your opportunity there as well. There's always risk!
