i know that maybe I'm just being paranoic, but bitcoin price will increase and I plan to hold it for very long term... then I can not stop thinking about if it is really safe or not. And if there is a software to monitor or transmit the data. Finally we have to trust the software manufacter. Maybe they are just waiting bitcoin to skyrocket and them clean everyone funds.
