You can't predict the price no matter how successful the ico was in past ico was multiplying your funds just by waiting for it to get listed on exchange but now there are various factors affecting the rogue one them is bounty.
It doesn't affect some ico but for more ico they give their tokens for advertising and the amount of tokens are really high at times because of this the price get's dumped whenever it get's listed on a exchange.
Another factor is general opinion if people actually like the feature and idea of the ico it will get pumped otherwise you will have to hold it until a product or prototype is launched.
As usual we cannot predict the price level of new coins as well the old coins. All the coins are being pumped by the decision of one or group of people. People do create fake demands which attract innocent traders to fall as prey.
Honestly the supply and demand alone must decide the price of any product but when the demand is being created by hoarding coins for the reason of increased prices then we cannot differentiate any coin from really potential coin. Devs sell their tokens from pre-sale to end of sale but we cannot find out where they leak their plans of pumping price levels.
