Hello all, I have been using bitcoin for about two years now but I'm brand-new to investing. I would like to jump on board with a few ICO's, but a question I have is when you invest do they have access to 100% of the money that is incested to them such as wetrust.io I see they have 533 bitcoins.  Is that theirs all at once? 

If so, it seems like a lot 1/2 million to hand over in one chunk.

Thanks
