Many flags - constantly failing to execute "full capacity", constantly postponing dates to be what they address to as being "fully deployed". It's a capital heavy industry and having many pre-paid and delivered expensive miners sitting aside unused is a sign of a poor time-and-money management. High depreciation and amortization resulting in an operating loss (check their balance sheet). Heavy incentives and compensation for the management, together with a stock dilution is a recipe for shareholders wealth destruction.

Stay away or short it. Best wishes to you.
