maybe this year ico will rise again, of course, with new strategies such as payment using existing coins such as ETH, XRP, BTC, and others.
I see several projects that want to raise funds and promote their projects to pay using ETH and BTC to their campaign participants.
I hope this will become a trend this year where all ico make payments like that.
even they operate again this year i dont think they can easily attract investors to invest on thier project because they have already a bad reputation in world of crypto.
