Top 5 money transfer companies plan to use XRP in 2018 according to Ripple :
1 - #WesternUnion
2 - #MoneyGram
3 - #TransferWise
4 - #WorldRemit
5 - #PayPal

For me I don't know why they would abandon the system there are using to jump on the Ripple platform, unless there are only going to be using Ripple for gate way to crypto space, the way banks think is that they want to own and have control over everything
