I want to make sure of one thing regarding the bonus periods as there is no specific end date for any of them. Also ICO starting date is mentioned but ending date is to be announced status has. You can't keep this open for unlimited time because everyone wants clear plans before joining. Everything is described is best way except information regarding token sale that is the area you need to work on to clear the things.
you're right, that's the reason I didn't join this project, yesterday I asked the same thing in their telegram group, and they said their IEO will end when all their tokens are sold out, and we don't know when that will happen, or maybe their tokens might not be sold out.
