Well choosing the good ICO projects to invest its really a difficult task but if you see the team where they experienced in blockchain or not, what they want to achieve with the funds, how it can be useful to us, product is there or not. if you can judge these things then am sure you can identify the good project..
I can recommend also to look at this ICO it's completed, so i am not giving financial advice, do check also about this.
Pledgecamp
Pledgecamp is the competitor of Kickstarter, it's a next-generation crowdfunding platform that incorporates blockchain technology for security and accountability. The company is building a comprehensive platform where Backers gain a decentralized escrow mechanism which protects their funds and creators receive wide-ranging project support and lower platform fees.
As Founder & CEO of Zuckerberg Media, Randi Zuckerberg also an advisor of Pledgecamp.
So you can Imagine how Pledgcamp is big..
