I see ICO appear around 30 in 1 day, but I see no promising projects yet
They like to see ICO where to raise money, whereas ICO has a heavy responsibility.
I am very concerned about this condition
You do not need to worry because the crappy projects will not be able to collect a penny. Now you can see a lot of ICO but only worthy will receive investments.
Yes, it's true. However, if the useless ICO projects raise funds, then the cryptocurrency market will throw out such tokens anyway, since they will not be in demand. Therefore, there is no need to worry about a large number of ICOs, only promising ones will survive, and this is very good for the development of cryptocurrency.
