It is a bit more about the fact that they could sell it for 2k and get a sold out in minutes. So that is why they do not consider it as a way to drop it, I mean why would they if they think that it would be sold out? At the end of the day if it doesn't get sold out there, it will get sold out on public and they will get that money one way or another.
The guarantee from NFT on Rollbit is investors and users will have real usability for Rollbit NFT, on a big casino with big trading volume. Bigger demand is better than unknown or small demand with NFT from a new company.
The reality is that if they do 10k+ NFT and each costs 2k to mint, then they would make 20 million dollars! And even though it doesn't look like that right now, they could technically do that and I believe that they could raise that much money one way or another, maybe not in minutes, but 20 million in few months is not that bad neither to be fair.
Points are if a successful and well-recognized company raise more fund, it is safer than a new compapy pops up and raises fund. It is certainly that there is always risk when you invest into any company, anything but investing into a new product of Rollbit, a successful company, casino is safer than investing into NFT of a new born NFT project.
