that's a convenient excuse, but they have promised things that they haven't delivered, like photos before hashing.
If they don't understand the market they are in (investment requires proof), then they don't have any business taking people's money.
It's obvious they don't have proof of hashing, or they would have provided it by now. The only thing remains is "why" they don't. Is it because they are a complete scam, hardware doesn't work, or what?
In any case, the stock is overvalued.
