I have noticed an emerging trend where at least 90% of new cryptocurrencies at one point in their first month of release to exchanges will fall way below their ico price so why don't I just wait for that point and buy instead of buying during an ico?
Centra just like the best example for your question. The dev doesn't locked the contract and the ico participant can dump their token as fast as possible nor buy in the cheap price on the exchange sites. But will better to buy in exchange site if the price will be more cheap rather than the ico.
