BTC is great for payments, you can use it to make payments in a secure way and also privately, all you need is to have an address for receiving and sending BTC to any part of the world. However, tx fees is a problem right now, with high tx fees it is almost impossible to use BTC as a payment option due to the amount you will have to spend in fees, though if you are making payments of a huge amount, or cross border payments, then BTC is a good option for that.
