I do know the largest SolidCoin holder, unfortunately it isn't you. Or I guess it could be you, provided you just move what you have to show us how rich you are.
But I'm guessing you never actually want to prove you are wealthy in SolidCoin, just imply it for some sort of social engineering reason. "OooOoo watchout or the spooky Bitcoinexpress will crash the market with his fake million coins OoOooo" .

Surely it'd be a huge tactical mistake for BitcoinEXpress to show her SolidCoin wealth prior to reaching well over a million coins if she is doing what she claims, because then you could take action to counter her? I generally reckon that it'd be safer for anyone intending to make themselves a trusted node in this way to present it as a fait accompli in order to deter the other trusted nodes from throwing obstacles in their way.
Of course any excuse can be invented for why he doesn't need to "Show the SC". Anything to cover the truth which is he doesn't have them. You don't think he could upset more people by showing he has as much as he says, or getting his "coins taken off him" by the evil mastermind (ie me) ? Seriously?
But like I said, any attacker will soon need over 12 million (up from the current 1.2 million) to do anything malicious (only 2.6 million minted currently), and they will also need half of the mining power. Good luck to them.
Anyone can do a Bitcoinexpress if they want.
"I have 6 million Bitcoins I will put them in escrow, if you do you can have them"
"I know important people"
"I control google search engine results"
"You seriously don't know how powerful I am"
"I just PMd your friends on facebook, you got doxed bro"
"I'm so important I created this alter ego called Lanie Grace to troll fans of an unpopular TV series called Terminator: The Sarah Connor Chronicles"
"I know SEO, it's like Karate for the internet"
What? You don't believe me? Booooo why not?
