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...
