For Newbie How check Which bounty program is good or which one is Scammed and i have heard that many good ICO still not launching there coins
it is difficult to distinguish between good and bad because most ICOs right now many to end up being fraudulent. I recommend for the beginners it's better to never invest in ICO and switch to IEO because that's it's more profitable. indeed not all IEO can be said to be successful but at least that's it is better than ICO for now.
Just as you say, not all IEOs are successful in this market, there are lots of IEO failures and many investors lose money, but it's still a lot better than ICOs. I believe that all ICOs will make investors lose at the current stage, if it is not experienced in choosing IEO, it is better to invest in altcoins listed in the market.
