Please accept my apology in advance if i am on different track while answering your question.
As of now, Govt of Nepal has banned all the crytpo currency mining or exchange and the Govt officials can hand cuff you and put you in the prison for just having some digital currency. That's just insane. After 5 years, you will also have the bank account in USA, correct? if that's the case you can just convert your currency through the exchange and put the money in your bank account and use it while you are in Nepal, though the transaction fee as well as the finance charge seems to be quite high, although it's not a big deal, i think.... Hope i did answer your question, if not again please accept my apology for not understanding the question
