It made some good points about how using the bitcoin currency is a good way to stay anonymous when trying to scam people. If you have them send money to an address, or account it's difficult to stay anonymous unless the account is someone elses and compromised. with bitcoin it's all virtual so anonymity is possible.<br>

Hi foofus members,<br>
<br>
First of all sorry for off-topic, but this sound interesting and I<br>
know that foofus guys are always playing with everything that is<br>
related with hacking and password cracking so I decided to send it<br>
here, I hope you don't mind.<br>
<br>
I never used Bitcoins and it's not very popular with my circle of<br>
friend, but a presentation entitled "Hacking the Global Economy with<br>
GPUs or How I Learned to Stop Worrying and Love Bitcoin" called my<br>
attention, however it's very confuse (at least to me).<br>

<br>
I'm a bit unsure about what is the goal of the preso and real usage of<br>
GPUs and hash cracking with bitcoins. The author gave the idea that it<br>
can be used as a botnet and since there is a lot of GPU systems it<br>
could be a wonderful network for distributed hash password cracking if<br>
the price to do it is acceptable (since Amazon EC2 is expensive).<br>
Anyone has any experience with it?<br>
<br>
Or, maybe the goal of this people is just use Bitcoin to be rich with<br>
all this power based on the GPUs "printing" money, which also is a<br>
confusing concept to me and Wikipedia say it may not be that easy<br>
anymore<br>
<br>
"The proof-of-work problems are especially suitable to GPUs and<br>
specialized hardware. Because of the growing computing power behind<br>
the system driving the difficulty to high levels, individual<br>
contributors with typical CPUs are no longer likely to solve a block<br>
on their own but can still receive part of the Bitcoin generated in a<br>
new block by contributing their processing power to a mining pool.[26]<br>
This increased difficulty makes it cost prohibitive for an attacker to<br>
perform double-spending attacks so it is beneficial to the system."<br>
<br>
All answers are very welcome and sorry for off-topic.<br>
<br>
Cheers<br>
