Current ICO market situations is very poor due to many scam. Those are scam most of them unsuccessful project, I mean they are unable to reach their soft cap. Some of scammer even sold their token, just skip after ICO sale. Any way we don't know who is sold out or not sold. Because even they are not reach soft cap, they already got money from people. They are not going to return anymore.
On this situation, before you attempt to buy any ICO you should read their white paper.
Focuse on their existing business. You should research about their business are real or fake.
Don't buy if there is no any existing business and they are make just new vision or new business.
So if there is well known company or business related with ICO, then it's almost safe to buy.
Note: Any ICO can be scam. They can skip after got money even there is good team members or what ever. That's why team is not much important for me.They should have well known business that can attract protencial investor's.
There are things that I always check before I invest in an ICO. The developers, project, white paper, road map and its popularity. Also, I am looking at the key investors. If there are big investors that invest, I know the project is good. Also, the team must be active to give updates regarding their project.
