Invest or not invest - that´s the question here

Maybe better invest after launch on exchanges? What´s your opinion?
The big chance is that the coin when entering the exchange will already be traded much more than the price of ICO, so people are in a hurry to buy tokens at ICO and pre-sale at a discount. And you can buy on the exchange after issuing coins for bounty.
Exactly, so if you invest now its really sure that you will get good profit once its entered the exchange. Invest now and gain profit later.
This is the best time to invest while the campaign is still going on, after the campaign you will say to your self that you did the right decisions.
