I cracked up when I read, If you donate 50 BTC, you get VIP status and the ability to create a custom title for yourself. This must be so outdated, thats like $412,599.75 as of today LMAO!
There was soooo many discussions about Donator and VIP ranks. Prices wont be lowered. Why? Because it would be unfair. In past people donated 10 or 50 BTC to get that rank, I don't think it would be nice to get same privilege by donating 0.1 BTC for example.
It's more likely that one day theymos will make new rank rank which you can get by donating smaller amount of BTC to forum.
