Moving abroad to a strange land is not something that easy and not everyone that made it abroad end up having the kind of life he imagined in mind to what could be referred to as a greener pasture. For some it even gets worsen when they finally travelled abroad as they may not have a good paid job or have to work themselves 4x more just to make a good pay for the week and end up having bills taking up 50% of it. If I could afford the necessary amount of money that can take me to go live abroad I'll prefer using that money to think of a good business investment to direct that money into cause in my country currency such amount to use in traveling will be running into millions. In this present day economic crisis no country has it better and cool anyway.

Don't overthinking yourself for you already have a good financial tool at hand "bitcoin", which is the new digital gold now. Plan on how to accumulatively invest in it periodically before your retirement time by then you must have made good ROI profit that you can use to establish yourself in some other lucrative business. Traveling abroad doesn't guarantee a save haven for all that does. @op think about it.
