In my opinion, Western Union proves to be a more secure way of money trading and paying, However, Bitcoin is far superior due to its low transaction fees, good security and simplicity!
Can you elaborate on what exactly makes you think Western Union is safer than Bitcoin when it comes to payments, etc? I really don't see Western Union having any advantages over Bitcoin.
Western union was hacked a few years ago and all the credit card info that they store was leaked and it lead to multi billion of dollars used underground by hackers,so western union is not safe to use.
