Bitcoin price is over $3200
Eth price is $250 and its ATH maybe around $350-$370? I don't really remember.
Some traders speculate about ethereum could reach $1000 but it's unlikely to happen in the near future.
Because bitcoin will take all of those attention from people due to segwit will be activated soon, at that time, the price could reach over $4000 within days, and maybe reach $5000 but not sure about the highest point before get corrected. When bitcoin price start to rise, ethereum will follow it I guess, just like what happens right now.
The last time ETH had a good rally because there were more projects coming in and so is the reason we saw a good rally and i really do not think that ETH will follow the price valuation of bitcoin all the time,there will be minor changes in the price of all the alt coins when bitcoin rises ,but that does not necessarily mean that it must rise when bitcoin rises. If there is some interesting news coming out regarding ETH then we could expect investors pumping their money in it,other than that i do not think we could see a rally now.
