Bounty Challenge 1
We (the Ex0-SyS team) have developed our own cryptographic Technology. We think that our cryptographic Technology is safe; by safe, we mean really safe. But why should you trust us? THAT IS WHY WE ARE ANNOuNCING THE next OPENING OF OUR BOUNTY CHALLENGE WITH A  reward OF 1 Bitcoin (BTC) to whom can crack US.

HOW it works

You will be able to download below an encrypted video explaining the procedure to claim your reward. The video is encrypted using [email protected] Vault Software. What we don’t give you is the Pin Code and the Password. It is up to you to download the application to understand how it works. Don’t worry, there is a free version! There are also some conditions to fulfill before you can get your bitcoin (the reward goes to the first person who reports the crack/exploit).
