I find this conclusion to sound accurate and actually quite funny.
You will never get your bitcoin back if you buy one of these at this price. It isn't even close. This is for suckers or those with stolen electricity.
not true since:
1. you don't know what bitcoin price would be.
2. you don't know what bitmain's price would be going forward.
3. you don't know what aftermarket price would be in early October or November
the combination of these three parameters makes it much less certain than you think.
BTW, people were buying S5+
