Thanks to all of you for your input, even the rude ones in this thread......... (come on people, said I was very new to this entire cryptocurrency stuff so no need for some of your asshat comments).
I found
http://www.badbitcoin.org very interesting (they even have a safe site list, was much more useful and short then the bad site list, just like some one in this thread said it would be).
I now know that doublers are bad period, too bad I had to learn the hard way to do so (I think I have a total of like $0.30 in my BitCoin wallet and tried the doubler with $0.07 worth of BitCoin so not a huge loss).
I have been doing a lot more reading overall through the forums here. Maybe BitCoin would be even more popular with there were less asshats in the forums being jerks with their answers? Almost enough to make me want to not try to make any BitCoin and give up on cryptocurrency so I doubt that I would be the only one that felt this way from the way some people do respond here.
