Wow 50 BTC that's alot, i thought they might have reduced the amount of BTC paid to become VIP , especially now bitcoin price has increased to a nice rate . Base on most users comment I don't think changing of one name would be easy at all , but I guess the reason why is like that is for safety reasons.
There’s a probability the request might not be accepted from what I read so what’s the point changing a user name, I think creating a valid reason still requires 50 BTC. Aside security purpose what’s the point changing a user name secondly why will any newbie want to think of such idea, I guess everyone deserves their freedom but things are done differently here so it will be better avoiding it or pay without a guarantee. The price of bitcoin has nothing to do with the fee honestly, if the price keeps increasing then good luck.
