We know that in the cryptocurrencies world invest are not 100% effective, because of the rise and fall of crypts, so much so that we are constantly interpreting the candles if they are in an bullrish trend or bearish trend.
but my question is about the ICOS, what aspects or information should I have to make a good investment in an ICO?
Well, if the ICO has a really good whitepaper and a great future ahead for their token, then it's most likely the only factor you need to confirm that it's a really good ICO to invest on. I would invest a lot on that token if they really have a great plan for the future of that coin. If not, then don't bother at all.
