ICO will die when new system of transaction,new system of managing money would be invented(this is not gonna happen in the next 50 years). And the another thing that many people think that BTC drops down because it will die. But WHY? This drop down doesn't means that it is gonna die. Everything has it's happy and bad days. Tesla considered as a loser, but now it's growing rapidly. And in my opinion ICO will not die!!!
