i think bitcoin is much more better than western union because bitcoin transaction is very much faster than western union and bitcoin bitcoin transaction fees is also too much lower and bitcoin is acceptable in anywhere nowadays because bitcoin is acceptable and available for shopping.
Bitcoin is definitely a lot better than western union in many ways and I think a lot of people will agree with me. Such as the fees being much higher and there is no anonymity with western union. Although I may be a bit bias seeing as this is a Bitcoin forum.
