I have some questions:
1- Is it possible one bitcoin address has 2 or more private key case of pigeonhole principle? if yes, we have to worry?
2- Bitcoin has been based on sha_2 (?), so break is possible theoretically http://eprint.iacr.org/2008/270.pdf
3- This money based on technology and new technologies are on the way, is it possible to have a hacked system in future?
