Im not going to talk about the ethics and risks of bribery, like most of the replies that you are getting, but I dont think that bitcoin is the ideal medium for bribery. Bitcoin is not a very common currency. You talk to the average person about it, and theyll probably tell you that they dont understand bitcoin. Of course, if you give anyone $1000 in bitcoin, they will still have the motivation to cash it in, but theyll also have trouble doing so. If you are trying to bribe someone with a usb stick holding bitcoin, it is too slow for them to verify the amount of bitcoin on the usb. Bribery should be quick and discreet.
Thanks for sharing your views. What if bitcoin is described as an P2P saving system? Do you think they would hold them.
