How often does the price get lower than the ICO price when a new coin is listed on its first exchange house ?
How come there are coins that are worth like 0.0004 $, usually during an ICO one coin is sold in the range of 1$ or not ?
Do some "coins" skip the ICO stage ?
This is really a basic question, and can easily be answered by research alone. If you believe in the value of a coin or project then of course by all means pour your investment into it. Just make damn sure that you did the necessary research and you can live knowing that it is your choice to either profit or lose all your money.
Buying from an ICO or exchange could be profitable or not, it depends on the coin.
