If he had an offer for 100k he should have taken it, if it was a real offer at all who knows. Someone above said the source is posted on Github, which means anyone could download and launch a similar service under a different name if they knew what they were doing.
Yea the game is different. But with bitcoin fads are here one day gone the next. Its only a matter of time before this site is old news and something new comes out that everyone runs to. Me personally I lost on Moneypots. Not a lot around .2 BTC, but still it didnt seem like anything more than a pick a number hope it hits that number game.
Not that I could afford to buy it, but that sounds like not a great thing to invest in. I mean basically it's buy my site, comes with attackers, hackers trying to ddos, people trying to harm me, thats crazy.
Just my thoughts on it... but who knows Im sure someone will buy it.
In a nutshell. Buyer beware. On the flip side, it's had great growth, it's got a great user base, and it's made in one month more than the opening bid.
