ICO is risky, but if you choose the right project you will succeed and become rich in a short time. But if you find the project unfeasible or fraudulent, you will lose capital. That is the pros and cons of ICO.
I think that trading is also too much risky, specially if you do not have enough knowledge and experience about trading altcoin, to me although i have spent a lot of time in trading altcoins but still i do not think that i have enough experience in crypto trading, i still need to spend a good time in crypto trading.
