Besides keeping it to raise in value later. There is not much I can do...
With fiat money, I can pay rent, go to restaurants, buy clothes. But with BTC, there is basically no stores that accept them in my country. Sure it's easier online, but then again the stores might not have the best products or is the cheapest/best value.
Am I the only one facing this issue?
If you have no idea what to do with your coins for now then you should just keep on earning it and store in a wallet because sooner or later it will be more valuable than what it is today. You cannot buy anything in your country as what you said so your only option is to store it because maybe in time, there would be a merchant in your place who would accept bitcoin. If you wanted to cash out bitcoin then maybe there is a way like sending it to Payza, Neteller or any exchange platform that you can exchange bitcoin with. For sure, there would be a way that you can cash out.
