I'm new to ICOs. I've bought into about 8 now and some release the coins right away, others I have to wait until the end of the ICO to get my coins, and ICOs I have to wait several weeks after the end of the ICO to get my coins (so they say).
Can someone please explain why they do that? Why not just give everyone the coins they buy right away, like some ICOs? And why does it take weeks after the end of an ICO to send coins? I don't get it.
ICO's have different systems and use different blockchains for distribution and storage. They might do it manually which takes some time or they might have certain bonus actions that consumes time for them to keep track of everything.
There can be a variety of reasons. If you're unsure or are expecting overdue coins then best is to contact them trough slack, e-mail or telegraph. Maybe they have a discord channel. Go pay them a visit and request for an admin and ask him/her to sort it out!
