Buying new listed ICO can get you insane amount of money or make you lose your money. You are taking a risk, but if the risk pays off you will never ever have to work again....
I think good if you can buy their coin b4 Ico end especially on first round price is mostly cheaper than nxt round, and if the coin is registered to the market when ico end you can sell coins, sometimes after 2 or 3 months if you Hold your coin
Staying on the ICO coins you want to invest, there are many ICOs that are higher priced but not listed in the cozico market are happening,
