Do people not realise that the whole point of cryptocurrencies is that they are de-centralised.
That means they can't be owned. It means that if Bill Gates himself launched an alt coin it would be about as competitive as Auroracoin on fundamentals. Obviously Gates-Coin would generate some interest on hype, but would have no long term advantage.
Look at Maxcoin. You could not have got a more hyped coin, and yet it sunk only a week after launch.
Billionaire launching coin = who cares.
Egocoin.
