Some friends ask me if they should invest in ICOs.
I always say for every ICO that they should ask the 4 magical questions:
    1) What is the size of the Market the token is addressing ?
    2) What is the role played by the token in the market ? Is central ?
    3) How capable is the team to deliver the token to be successful ?
    4) Is the Hardcap Vs % of token distributed reasonable ?

If all the 4 questions have "yes" as an answer, "go for it".

For the current ICOs that you are investing, I would you answer to these 4 questions ?
