I think the price is as good as it gets right now. I would suggest investing right about right now. Always try to remember to put some stop loss so you do not get bummed out if the price falls. In that case if you put something like 5% or so in stop loss you will get your cash back with a small 5% loss (who hasn't had that much of a loss in crypto) but if it goes even further you can recoup more ethereums later on and hope that when it goes up again when the 2.0 happens you will profit much more.

That is the defensive strategy of course, keeping the coins and putting stop loss, there is also offensive strategy where you keep on buying the more you can afford, don't just let it be at one entry point, price always changes, have multiple entry points and you are safer.
