Well it appears there are some Chinese dedicated to reselling, so first they buy all they can from the manufacturer, and if they succeed depleting supply, proceed to resell at much higher price. Especially when the manufacturer has still not increased production and the price of bitcoin is high... Should the price go down, those re-sellers are going to find themselves in trouble.

Which is how we ended with 1200$ S17 being sold for like 4000$... Supply and demand i guess.
