yes, rest assured that ETH prices will rise even though it's quite slow. I feel that the price of ETH will rise slowly until it is above $ 500 again. if you don't think about investing, then think about how you can get, or collect ETH.
I await a rise that, because I myself believe ethereum can ride and deserves to cost more than current prices. I put together some of the ethereum of bounty and bought some yesterday. I am preparing myself for the increase to come.
I think that $ 500 is a huge number at the present time. ETH's price now only fluctuates at $ 135-141 and it seems to be stable there.
ETH takes a lot of time to develop and makes its price stable at $ 500. I estimate ETH will be at $ 500 by 2022.
