Why, when we receive new coins for a purse, they are not traded for a while or for a long time on the stock exchanges, why? What do you think about it?
First of all coin are not exchanged in STOCK exchange but in crypto currency exchanges.
In most cases project' s management does not want to go to IDEX or other semi centralized exchanges because they want minimize the risk of price dumping in low volume exchanges thus they apply to bigger exchange and this takes time , effort and money.
