1 / ICO not the attention of the international community, no traffic ==> absolutely not play
2 / Introduction of profit will be achieved more than 50% per month with short period (less than 200 days) ==> consider when investing
3 / ICO selling day: open day less sellers (such as Bitrooz, ..) ==> track 1.2 round and then play, do not play
4 / ICO sharks buy with rate x2, ..x10 compared to the time ICO ==> consider when playing, do not hold by hold to die (eg GoldBankCoin, ..)
5 / Do not keep up the road map for a long time ==> close high risk
6 / Change the form of investment compared to the original introduction ==> Signs of stopping the game (the most recent demonstration is the Bitconnect stop lending event)
7 / Coin (ICO) prices fall down steep and long time not increased ==> lose value
8 / Issue in the country forbidden forms of capital mobilization ==> close to close
