Their business model is one thing, but you have to agree they haven't scammed anybody yet, and they've been operating for how long? 6 months? I wasn't even on the forum back then.
They gave people who ordered vaultbreakers free hash in the cloud weeks before the titans shipped, so they delivered in a way.
Also, I wouldn't call a data center and a domain a flashy thing with little purpose. IMO a scammer would not invest at all, just send a few miners to get positive feedback, launch a big preorder event and run with the money.
Woot because not having scammed someone yet in all of of 6 months is the surest sign of not scamming one in the future. You are trading an irreversible payment for a reversible promise. The longer the time frame of that reversible promise the higher the chance it will end up being broken. For good examples see every single asic manufacture to date but hey gaw will be different.
The bigger the data center the larger the fixed expenses are and that needs to be earned back. At a certain point it will be more profitable to screw the customers then to continue operating. At that point your hope is that people will be honest and work for free instead of going BK. Good luck with that.
