EOS is a token to hold if you have a long term view. The ideal situation is to get as big of a percentage stake you can at the cheapest price point you can
Would you like to estimate the value before you send the money?
Does EOS token worth 1$ or 5$?
When using exchange markets the price is known before you buy.
Now you can estimate market cap value during the first days of the ICO and decide if you want to buy or not
Look at the address first

As of now 16.2m has been raised by eos in first day.So
Amount of money raise÷Total number of coins
16.2m÷200m=.081$
This is price of 1 token based on the first day
There is also yunbi which raised 150000 ether

My advice would be to find out the money raised then decide is it in your price range or not.
