There's some ICO which announce crowd sale that lasted longer than others. What does it signify?
Following that question, would you consider the duration of the different stages of an ICO sale? (e.g. a long angel round, or a pre-ICO sale that is very short)
Does it make a difference to you?
I think that in good ICO projects change the terms of different periods because the creators see that they can not raise a certain amount during this time. And maybe they believe that over time the price will grow even more.
