the alternative way to invest in new project is investing on IEO because all of fund are escrow by exchange.
but we can hold or boycot some new project where they decide to launch ico for funding the project, this is the freedom of blockchain community, people can do anything what they want
You have the right thing to do in your own way but you don't have the power to boycott ICO because there are some few project coming from ICO that are still surviving even if the market is experiencing a dip down. Things to learned is that its not a problem of ICO making unworthy or bad thing in thread its people who fooled for.
