Will I be able to cash out and at the very least support my livelihood if I pursue Master's degree in countries like USA, Germany or Australia? I dont want to do odd jobs, only dedicate my time to studies and maybe trade a little when I need to make cash.
How much savings do you reckon is needed to survive for the 2 year course as a student? Will cashing out and such be problems being a foreigner?
You should probably attempt to cash out a hefty amount prior to moving wherever you do end up going, because sometimes exchanges have a tough time working with visitors/immigrants, there might be delays or difficulties, even grey areas that you may have to overcome. I lived off of my bitcoin stash when I went through a tough time in other areas of my life. I made 2-years, on about $25,000 while i was pursuing a degree, eating pretty well daily and enjoying some nights out at the bar.
It's almost impossible to tell you how much you will need, because everyone is accustomed to a different standard of living. $12,500 a year in a country like Germany, or America might sound crazy to you, be it too little or too much. This question is similar to "How much $ do I need to live 1-year?", it has a million different answers and none of them are wrong or necessarily right. You should create a budget for yourself, figure out how much your living situation will cost you, figure out if you're going to have a car, how much you're going to spend on food (don't estimate, look up recipes, ingredient prices and even local restaurants). Once your figure out fundamentally how you'll be living, and where it should bee pretty easy to throw together a budget and figure out almost down to the penny how much you will need to make it. I would bring 10% extra, whatever you decide is enough, bring a little more just to be safe; and while you're doing the budget you should figure out what it will take to cash-out your coin if you should need to in the future.
You cannot hit a target you are not aiming at, so make a plan, set a goal and make it happen!
