Hello, let me clear this doubt some people said that all ICO is a scam but I don't believe them because I have invested in some ICO and make a good fortune, let me give you some clue to invest.
1. When you want to invest first of all research about the particular ico you want to invest in, try to check their Whitepaper because some ICO copy text from another ICO white papers
2. Try to check their LinkedIn profile though that does'nt matter because some fake LinkedIn profile.
3.Try to know their real location even though some use VPN to hide their location.
4.website professional matters a lot because some don't even know how to build website and they are claiming that they are in to Blockchain
5. Despite all this..involving in ICO is a big risk
Not Just in investing in ICO, but also that any investment has its risk. So we should not be carried away by some enticing words, rather do our own research and be sure of what we are into.
One of the things i always look at before investing in a project, most especially on the part of website. If the CEO or developer of a project cannot give a good and mature website, i can't trust such.
