I see and observe recently that many ICOs are below the ICO price when they touch the exchange. Do you think it's a smart step to wait for an exchange and buy the tokens you want?
It all depends on the hype of the project, bro. For many projects is better to wait for exchange listing, as bounty hunters and early investors with high discounts might liquidate their tokens for a quick profit.
However, if the hype is huge (see BitTorrent) the price will increase significantly when the coin touches an important exchange.
