Well, I'm a bit jealous for staff/moderators/VIP/donators who have another custom name/rank below their usernames since I can't afford to be a VIP/donator and there's no way I become a mod or staff, so at least another custom name/rank below my username "Copper Member" is the best way to overcome that jealousy 
And, say, another way to support the forum.
As I said above, for example, the Copper membership costs 0.005 BTC at specific time, ie. and in fiat it is insignificant now. Let's imagine sometime in the future, next 5 years for example, 1 BTC worths $1mil. I don't think people who bought the membership will decide to take off their title. And, say, another way to support the forum.
