I guess now is too late for investment in ethereum. I believe one day it will reach $1k but I don't think this is going to happen this or even next year. That is why now it is better to stick to cheaper currencies like litecoin and maybe xrp, for these have potential to grow in a few times in about a month or two from now. There is huge risk in buying eth now, I guess it is better to do that at least after a successful switch to pos, for let's not forget that eth can still crush.
