Biggest hurdle thus far has been more emotional than anything else. Missing friends and family members, but writing and staying in contact helps.
I’m traveling with the Mrs, so that also is a big plus.
At first, best to go to places you know and are familiar with rather than going some where entirely new. Lessens the impact.
With Bitcoin, a lot of places still don’t accept; so ATMs and gift cards are your friends. Yes, high premiums, but that’s the true cost of your coin.
