Thanks for all your inputs. It has been helpful.

Hi,

We have plans to use bitcoin as an online payment system for international trade. I have been looking for the security concerns on using this payment system. I came across a video blog about the threat of botnets. http://www.storagepipe.com/blog/DDoS-Bitcoin-Brute-Force-Malware/

So, in such an event, what protection would help me? Will an ordinary antivirus protection prevent such attacks? Please share your suggestions about it.

Also share your opinion about using bitcoin for trade.

Thanks in advance.
