So I'm not those last moment type of people i always keep sufficient savings. Currently the money i have in bank will be sufficient for me to live in my home country for 4-6 months including ticket fare. And 1-2 months in foreign countries. I also have funds in bitcoin and few alts so that will also help.
Its always good to have an habit of saving money either in bitcoins or in fiat as it will take care of you in emergency situation and you don't need to borrow money from your friends or family as your savings will take care of you if you need money desperately.
Luckily I have that hobbit. I am from a country which is not a very rich. getting job and earning a good money is very hard here. so we are naturally saving minded people. any time we get more than our current need we'll save that funds. which is a good thing I think.
