It stops here.
Stop supporting obvious ICO scams. Don't add them to your signatures. Speak out against them, and stop defending shit coins. If we want to get more people involved in cryptocurrency, let's stop spreading these absolute shit coins and spend our time on what matters.
If you support this and are ready to stand up against these obvious scams by not selling out your signature to shit coins comment below.
But the question is, how do you define or judge a coin to be an obvious scam? I coin that may look shitcoin to you, may look very promising to its investors or supporters. There is no base criteria where all can agree or evaluate about an ICO.
