How to join the sale,whats the procedure,do you have some explanation video or article?
The procedure for participation in any ICO is always almost the same, and it's very easy. You can watch any video in YouTube, there are a lot of them. And if this is your first participation in the ICO - then be careful, do not invest a lot of money.
Are you talking about general ICO participation videos or about Agate videos? Because Agate has only 2 and none of them are an explanation of the participation process. They should make a couple of short videos for that purpose. The community would be gratefull.
