There is no choice for us until if we don't see any progress. Most of the ICO, are getting into scam without further updates from the company, during the ICO the marketing will focus on marketing the product but failing to develop after the ICO.
This do results on seeing lots of shitcoins in the market because when a certain coin is listed on exchange developer do tend to leave it and dont make any updates which i do see its much better compared to those projects or coins that didnt even hit up on exchangers.When we do talk about bounty scam this is the most common thing where developers do make because making money is quiet easy specially when fooling out investors.This is why we should really be careful on investing.
