50 BTC! OMG! 
Are you serious really? Please consider them for a discount. Paying 50 BTC should have been possible in early 2010. 
Yes, 50 BTC. The price should not be adjusted and it will always be the same. The USD equivalent is a pointless measure. Are you serious really? Please consider them for a discount. Paying 50 BTC should have been possible in early 2010. BTW, why is it restricted here? Is changing a name really bad? I have been on other forums and I'm easily able to change my username and also the previous username histories are shown! Please tell theymos to help me out! 
Because of various problems, like impersonation, scamming, etc. Theymos will definitely not answer your call for help as the username change is requested without a proper reason. I think you are trying to tell that no same usernames are allowed. But I think there is no username with "Donkey Kong". Can you point it out please? If there is such username then I'll surely close this thread.
BTW, I think scammers can always scam with any username so there is no point that I'll become a scammer if I change my username and I won't become a scammer if I don't change my username. I think you got my point. Let's see what theymos says.
