I guess this kind of sums it up:
Has anything been written anywhere about the reasons for this? I can't imagine it's a money making measure. I also can't imagine it's going to deter the people who aren't already deterred by it.
It's just that I last changed the price when the BTC/USD price was $12k, so it's drifted from the intended value. Evil fees will also be updated.
The price will be fixed in bitcoins so imagine what will happen when we enter a bull market again.
Then I'll (eventually) adjust it downward again. I like to keep the BTC-denominated price pretty stable and not change it every time the market freaks out in either direction, but it's supposed to have a vaguely consistent real value.
I doubt that the Copper Membership aggregate per month adds up to too much really.
Edit:
If I compare @Piggys last two full user database available dumps (beginning of November and beginning of December 2018) weve got:
November reading: 3994 Copper Members
December reading: 4411 Copper Members
That is a net of 417 Copper Member is a month. At 0.00208333 BTC or 7,5USD equivalent, its 3.127$.
If monthly subscription was to be the same after the increase in price (which it wont I figure), its roughly another 6K per month of income (9k in total - ok, good enough to add an extra programmer or so).
