If you care with profit, just take it. It's so simple for me, take it or leave it. If you're not ready to loss then don't go on IEO! Look another option such as trade, which is too risky than IEO for me. The trend is IEO nowadays so why choose another option?
I agree with your premise on trade. Its quite technical and more risky than IEO. All you have to do with IEOs, is find a suitable exchange with high returns on investment like gate, Binance, Huobi and Okex, hold thier tokens/coins and give it a shot. One thing is certain, if you manage to get in, your ROI will be high enough to cover any losses that might or will ever occur
