BTC is way better than Western Union because of low fees. It's possible to send much lower amounts without fees
and you do not have to go anywhere to send money you only need gadgets and internet then you can send money anywhere in the world. This is far more sophisticated than WU
This is what I have in mind when I saw this post. Bitcoin is pretty easy to transfer and has low transaction fees the only downside is that sometimes the transactions take a long time to be confirmed and some people don't want that, they want instant money. For me, I would still prefer Bitcoin.
