I think one of the reasons is that these ICOs are really enticing and promises big returns. Most of of them are lending platforms that encourages beginners to invest.
I really do think that ICOs should be like that because if they won't be so smart and creative especially when it comes to their advertisements how could they attract people to invest and participate on their project. It is just their marketing strategy that they should look big.
That is right. I think the crypto currencies investment is still very risky. So it is better to be invested by the experienced and informed users, not general public.
You have a point there but for me the reason why there are crypto advertisements is not for people to invest right away but mainly to give awareness that such digital coins exists. Social medias are a good way to spread awareness so it is juat reasonable to think why there is so many crypto ads around.
