Its still hard for me the belive that sp20s made SP-tech no money.
It did ... but towards the end it didn't (As I read the situation).
Take into account R&D costs, production costs, shipping costs, staff costs ... and all the other miscellaneous costs that a business has ... and it all adds up. Bitcoin also tanked during the SP20 lifecycle.
Sponds aren't famous for bending the truth, and why should they? SOLD OUT .. and things were tight financially towards the end of the shipping run.
If you have inventory, and need to get it sold ... sell it and get the money in, basic business sense. You don't always make a profit, but money in the bag is better than none.
