it is not a good idea to invest all your money in one ico because you can choose many ico in out there but you need to know the details of every project so you can make a profit in the long-term. but for me, I think I will use that money to buy the coin in the market because I am not sure that I can make a lot of money from the ico. my advice is you need to split your money to three parts and you have $1000 to buy coins, $1000 to buy ico if you really to invest in ico, $1000 for your back up money if the coins you bought gets down so you can buy another amount of the coins.
