They built the vault supposedly for Nick to stream from, but in fact, it is reinforced and basically a nuke-proof bunker. They plan to use it after the acoofalypse to run the white supremacist rape army that takes over the world.Oh my God...it all makes sense now! The real reason why they started the GoFundMe was to funnel the money into Nick's house which Ty Beard owns! Perhaps the grifting game was weak and they had to find a way to finance any renovations they wanted to do, so Ty had Nick refer Victor Migogna to him and start a GoFundMe under the pretense of "legal fees".
WE HAVE FIGURED YOU OUT NICKY.
