The machines are already worth virtually nothing even if delivered today.  They have a 0% chance of RoI.  A month from now, the hash they produce won't even pay for the "supposed" 300w power usage.  Odds they will deliver within 5 weeks? 0.  They just can't pull it off that fast, they are MONTHS behind schedule, not weeks.  They outsourced everything... EVERYTHING and "hoped for the best".

Unfortunately, I paid in full... because of the threats that I'd lose my deposit if I didn't.  I also paid both in bitcoin.  Odds of me seeing Any of that money back? 0.  Could I win a lawsuit? 99% chance.  Would I be able to collect on that judgement?  Not a chance.  If they find a way to actually produce a product, they would declare bankruptcy to wipe out their debts, sell their business to themselves, and create a new company with no debt and a working product.  Seen it too many times.  That's also how they would "stop the business from being in existence" to wipe out your shares.  If it were even legal for them to give you shares to begin with.

Never risk more than you can afford to lose: and I didn't.  I've taken a number of risky crypto based investments, and I lost about the same as I've gained in the last 8 months.  Might have lost a couple hundred, but not that big of a deal.  This... I've written off as a 100% loss.  But... I've gained knowledge and wisdom.  Don't buy something that doesn't exist.  Don't buy ASICs EVER.  There's simply no way to make your investment back, simply based on the quantity these multiple companies are producing.  No matter what the speed is, if a company sells 10,000+ units of some Super Asic, the difficulty will rise so high that even the super Asics no longer makes it's cost back, Ever.  It's guaranteed self-obsolescence.
