I'm not sure what chart you're looking up, but ethereum now is worth about $102, it has been fairly stable between a range of about $6 for the past 48 hours.
Hopefully we have hit the bottom and colan only go up from here. Don't hesitate to much when investing, there would always be better times and worse ones.
Yes there is nothing to hesitate about when it comes to investing in Eth. I would say that investment right now would be the wise thing to do because it will yield high and good profits.
