Also, as has happened with others, there just arent enough margins to give everyone more hardware to compensate. Its not like these things have 100% margin so you cant just double up the supply. Those days are long gone (avalon maybe even kncminer had great margins, the first time around... but the more recent asic companies have operated on much slimmer margins... and their costs are high because every part theyve ordered has to be on a 'rush' schedule which means everything costs a lot more than if you could give the suppliers the usual 12 weeks to source the parts (an eternity in bitcoinland)
Thank you for another insight on why are pre-orders needed for a new company that already invested in 2 mask sets and on parts for their gen1 miners.
if youre talking about sp10 versus sp30.. theyre completely different products. theres little similarity. the sp10 uses large amounts of small chips, kindof like the antminer/bitfury/asicminer whereas the sp30 uses larger more powerful chips. has a huge knockon effect on board design (higher power requirement, cooling etc).
Also, since the SP10 was only ever sold from stock (never pre-ordered nor pre-announced) so we didnt know whether its performance on arrival was as simulated as that was never shared with us. SP had the luxury of delivering an in-stock product, where you know what it does before you sell it so everyone gets what they expected and is extremely happy(!).. whereas the SP30 was a pre-order scenario with high expectations (and risk) from everyone concerned.
Also, as you know... pre-orders as a business model are pretty much over now. too many punters (AND asic companies) have got burned or scammed and the punters are as much to blame as the asic companies... (many punters play arbitrage games with their preorders, and cancel orders when the bitcoin price drops and becomes more attractive than the miner they ordered. its a tough market for asic companies to deliver on expectations in the pre-order game, and its tough for customers to trust asic companies. ergo, the pre-order market is pretty much over.
