It's currently $$265 on coinmarketcap and i think it will go lower. Now should not buy ETH. Be Wait after 30th, Sept
Do you mean it will go lower because of Chinese exchange ban or is there something else happening on September 30?
Never, Because this time a lot of the ethereum project are not allowed the chinese to participate in the crowdsale. But if the more update to the ethereum network will have implemented and that will be no a reaosn to the price should go lower.
