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.
That's what will really happen. Investors already have trust issues, so I don't think that ICO's will rise again. Even if something new came out and will make ICO trend again, investors will stay limited as they will try to avoid this thing again.
