I have few concerns regarding this, say BTC does Hit 100k suddenly (like it did when it jumped to 19k about a year ago) at some point, will Any Exchange actually accept buying my ONE (1 BTC) and give me Cash 
?.....
Which Trusted International Exchanges should I deal with to sell my BTC in exchange for Fiat ??...
I am from Dubai, we have here a website called Bitoasis, but am hesitant, I have a feeling that many exchanges will refuse buying my BTC for real cash WHEN BTC hits huge numbers 30-100k $...
plz correct me if am wrong...

Yeah. Why would they refuse? Services that buy and sell bitcoin makes profit regardless of high or low bitcoin's price is as they have their own price cuts. It's not like they would hold(or hodl) the bitcoin. Those kinds of services pretty much automatically sell the bitcoin they buy and vice versa to protect them from the volatility.
