Also, you might want to pay attention to the fact that the length of time for them to sell a batch increased a LOT when they moved to the "require payment in BCH", even though Bitcoin price was still rising at the time and demand was still INCREASING.
Instead of "sold out in a few minutes with massive website clog delaying the sales" they went to "needed a few days, then needed weeks" to sell out a batch over the next 2-3 batches after that - DESPITE a still huge demand level.
Not quite true. I bought my 14TH units on 9/27/17 and believe they were the last of the BTC accepted orders. Within days of me placing that order they had switched to BCH. So all of the 2 minute sell-out actions that happened in December and January were under the BCH flag.
I know it has cost them a few sales... I was about to buy (12) more a couple of weeks ago when I found myself 0.25 BCH short. By the time ShapeShift converted some BTC for me, my order had timed out. By the time, a few days later, when I got the associated coupon situation under control, BCH had dropped so far it didn't make sense to buy.
