I have two questions:
1. Will the price of a copper membership change if the price of a BTC rises sharply?
Probably. I can't find back the link, but theymos said similar to that.
Here.
People now - "No way I'm paying $65,000 for a Donator membership!"
People in 10 years - "No way I'm paying $65,000 for a Copper membership!"
Unlike the Donator/VIP memberships, I
do plan on reducing the cost of copper membership if the price rises a lot, so that shouldn't happen. (Though the membership price doesn't float automatically.)
