In any normal transaction proof of funds is something that happens right at the very beginning of the process. I can’t imagine this case being any different.
So why the total silence from the club if it’s all bollocks?
It's the whole ambiguity of everything, theres fuck all verifiably true information about this whole thing. So people can assume whatever they want. There's no proof they have actually provided proof of funds, they haven't even stated themselves that they have done this.
