I don't think the inability for ICOs to be successful these days is mainly due to drop in bitcoin price. There are a lot of contributing factors. The numerous scam incidence is even a major factor which is preventing people from investing. All the same, those projects with promising mission and vision will surely survive no matter the price of bitcoin at that time
He if the project can promise so that it can run well and smoothly
ICO can be successful if the project is truly high quality and there is no ICO fraud, of course it will be a good opportunity.
maybe in the future ICO will be better so don't despair in trying to join ICO, of course choosing a good project.
