And western union can easily be hacked...
If you have seen, i have senn many hackers hacking western union money WU and selling them in change of btc..
Because they can't hack btc or they can't use stolen cards there..
The blockchain is too much secure than other all..
That's why they sell hacked WU transfer in change of btc..
And btc has fast transaction, lowet transaction fees, and open easy use, no government controls..
