If I look at your question, it will be very difficult for EThereum to be able to bounce back like last 2017, but for the current increase all this shows a positive thing because prices in 2017 will be repeated this year but note that Bitcoin prices continue to soar.
yes, even though it's difficult but the possibilities still remain. ATH for ETH is considered very high if measured from now. however, I believe that the price of ETH will rise little by little. this might make the ETH price even higher, and could approach ATH ever achieved.
If the bullish market keep continue, i believe ethereum price will increase, not ATH but slow buy sure it will go up. Ethereum price is at $240+ and if nothing bad happen, pretty sure it will reach $300 soon.
10x is too much, it's not that easy for a coin to increase to 10x.
