Re: DoubleBot.com - The only one place to double your BTC with a 100% guarantee.
very cool. after the percentage drop there was no way someone could reach 100% till now (or at least a very little chance of that) so if we think a bit more we would not be so surprised now 
You could see that site pays every day, so, a lot of guys even after the percentage drop reached 100%.
There are some problems on a server.
sites not paying anyone site is down .
