Plan is to invest it into Ico's that i find interesting, maybe 10 ico's.
Should i be investing straight away due to the upcoming metroplolis updates next month?
How do you reckon the price will go over the next few weeks?
I'm seeing that Ethereum is getting dumped a bit now so it's not a bad time to invest even though if we check the price for a week or a month it's really high.
Dumped for the month being yes, if you're looking for longterm, i'd say anytime is a good time right now to buy eth. Due to relative currency strength it's value will rise with bitcoin in $ most of the time anyway.
My guess is that in a few months you could either pick it up for under 250$, or for over 500$. September is going to be a rough month for eth.
( FED gov bankruptcy and possible POS https://www.coindesk.com/ethereums-big-switch-the-new-roadmap-to-proof-of-stake/? ) could make the price of eth increase by ALOT.
