70$ will be ideal price to buy eth though I doubt it will fall that badly. It's one of the best altcoins and second-best after bitcoin. Problem with altcoins is that they only go up when bitcoin goes up. In the next bull run, I hope eth will take some decent push.
it could have happened if bitcoin at the beginning of the year fell again. although an update in the year does not rule out the possibility that the market could decline again. we all hope for the best for the crypto market. but we also have to prepare for all the possibilities that could happen in the crypto market.
I did not think we would ever see ETH below $100 but it happened like twice this year did it not? I think even at today's price you can not buy enough ETH if you are a long term holder. Once 2020 passes and 2.0 is fully in place, we should see ETH go up slowly and surely towards $300 and then one BTC does its magic, we should see the best altcoin in the world move up back towards 1k.
