Theymos has said in the past, that he does not intend to lower the cost of VIP and donator accounts. This means for all intents and purposes, no one else will ever purchase a VIP or donator account from the forum. Theymos has said that he may create additional paid memberships in the future. The Copper Membership account costs about $35, and the cost is periodically adjusted for the price of bitcoin.
The price of the Copper membership is now closer to $25. Not sure when and how often this changes. The reason the copper membership fees change is because the forum wants and expects those to be bought.
As I mentioned before, theymos manually changes the price of Copper memberships so that it has a fairly consistent cost in USD.
That can't be said for the VIP and Donator tags. theymos knows very well that no one will ever pay those amounts again, and even if he lowered it to 1 BTC each, how many of you would pay $60 grand to get a special tag under your username? And please don't tell me that 1 BTC = 1 BTC. If you want me to believe you, go out and buy a loaf of bread for 1 BTC because that's how much it was worth back in the day. Or pay 10 BTC if you are a true hodler. Where are those receipts?
IIRC from reading old threads, the cost of a VIP membership was approximately the cost of one month's hosting. The forum's hosting costs have subsequently grown, but not as much as the price of bitcoin.
There may be an argument to periodically change the cost of a VIP account to be in line with
x number of months worth of hosting. This would probably lower the cost to be several thousand dollars, but would not be anywhere near the millions of dollars it costs currently.
