As we all know that bitcoin now are being made as a trading pairs to different fiat money all over the world. And we you go round the world having a good vacation on different countries you do not need to bring more fiat or physical money instead bringing gadgets and connecting to internet is enough to get fiat money after it will be traded to local exchange. In this way there is no need for one to bring more physical money as bitcoin could unify all fiat money around the world as trading pairs.
Um..sure that could happen, but for that people should adopt bitcoin. I would like to spend my bitcoin, but not by carrying my hardware or my pc, but by using my phone. But here's the thing, I could get easily hacked, like its not worth to be honest, there are more negatives than positives which is a big bummer. I do use my bitcoin for buying various things, when I can, but I would refrain from using my bitcoin on vacations, its not required. I can just fiat, and not have any issues, you know?
