First it was my bank exclusively for traveling purposes. It offers decent options for payment abroad and deals to get the most of your spendings while traveling.
But now I use it not just for that. I created several sub accounts to make my spendings more efficient. All of them were set up a certain way so that it's almost automatic. I have very little participation in the process.
Sme questions could be raised about the withdrawals and the free limits. However the thing is this bank is operating online predominantly and the people who use it have their needs online too. In this regard everything makes sense to me.
