Using Ethereum While Traveling

I posted this on r/cryptocurrency and the responses weren't very helpful so i figure i'll try here. are there any sites to link up with local crypto buyers/sellers? i want to travel to Colombia and Peru and use my crypto to get cash upon arrival to each country rather than using an overseas ATM or a currency exchange. i see localcryptos closed and i can't find a suitable replacement.

side note: is crypto even remotely used as was initially intended (p2p electronic cash) or is it all about ETFs/store of value now?
