1 and 2 are simple rule that everyone knows even an idiot. In the forest of ICO nowadays, no stupid guy will invest in such project as in 1 and 2.
you might be right. what if an ICO site just put up fake members on their site. like if you contact them, no response will be received? or if there is, it's doubtful. you can feel it because you are not an "idiot" right?. it is simple for you because you already have been engaged with this, however, there are still people who are victimized with fake or scam ICOs. they just tend to take a little look at the site, consider the price of the token, red few, and invest directly. they are people who don't have a vast knowledge about investing in ICO like you are.
