Hi, I am interested in changing the online payment system of our organization to cryptocurrencies. I have been reading several journals about it. Recently, I came across the security threats of bitcoins. I watched a Video blog about botnet attacks on the bitcoin attacks and how easy and likely it is. http://www.storagepipe.com/blog/DDoS-Bitcoin-Brute-Force-Malware/ I know that there has to be some kind of security measures that can be taken up to protect from these threats. Does anyone know about it? I would great appreciate your suggestion and advice.
