ico's are high risk high reward thing but the risk factor is above 70% that's why i never joined any ico... your money was locked until the ico ends , let's say about 1 month without any good ending as this is the history of all ico's... if i were to trade that money for 1 month it could triple or even more than putting it on ico....
Until now ICOs have been good to me but it requires patience and good research.
yeah ICO's are not a bad thing and it is really rewarding if you do it right. but in my experience i earned in ico though but i could earn even more if i just watch the price of that new token instead of contributing and locking it down.
