Only 13 days left for this month. ETH still hovers around $430 mark without any indication that it could break $500 price mark. To hit $700 or $900 at the end of this month is impossible. I can't think any scenarios that could help ETH come close that price mark in such a short amount of time.
It certainly won't happen, it's just a bullshit prediction and there's no basis in this market. I see hundreds of predictions like that but none of them are really accurate. Invest on your research and don't trust anyone or you will regret it
