I dont know how a newbie learns so much in a few period of time
So, why do you think he is a newbie in crypto world? Just see his rank in this forum. Almost potential investors in this forum, but not ALL.
I know that most of todays traders are here just to make a quick buck...
I think you should call them "investors". Traders earn their profits from trading, not in investing.
Who is investing in those ICO's, what is the one thing that lures the todays investors into investing in a certain project?
As I know, almost really potential projects have their existing partners, which is the companies or organizations. And these partners ready to invest a part or all tokens which are sold in pre-sale or private sale, even helps this ICO reach the soft cap instantly. Because it will ensure this project will be implemented. In addtion to attract other investors because this ICO has already reached the soft cap.
But about the not-potential projects, I think there will be investors who believe in these projects and invest in it. Maybe it has a long time to reach the soft cap or even fail.
About what is thing that attract investors? I do not know because everyone has their mind. Personally, I will notice their team + advisors and the solutions.
