there are lots of good ico but some are scam. we must be careful to choose it because it will affect the results that we will get. if we can choose the ico well then the results that will be be obtained are also good. but if we can't choose it well we won't get the results.
Been careful of an ICOs investor is not enough and it doesnt guarantee that the person wont end up scam because an ICOs investors must know what to look out for before investing into any project. However, there are bounty campaign manager on here which I studied and they host genuine project. I recommend people like Yahoo, iwantapony etc. I will create a thread soon which will help ICOs investors to choose right project because the scam ICOs are those that make STOs to take over ICOs.
