ETH can rise even from the ashes so I wouldn't worry about the current price of ethereum. I invested some money in ethereum this week because I consider it has a great buying price.
Now it is really a very good price to buy, but I put orders for 70 - 60 - 50 dollars. I expect that the Ethereum will fall again. After 50 dollars in January, it will rise till 300 and then fall again to 150. waiting for my money)
