Venezuelans cannot accept USD without a bank account. You can use paypal but its hard to exchange from paypal USD to the venezuelan currency (Bolivares)
Coin Metrics says the transaction fee stands at $7.67 which is astronomical. ETH is a bit lower at $1.39 but that is still far far higher than most payment instruments.
I'm not sure where you are getting those figures from, Coin Metrics shows fees under $1 for both for me [0]. The two sites I've used in the past that have been pretty accurate show ~$0.10 for both [1] [2].
I don't use BTC much these days, but if you're paying $1.39 for an ETH transaction you're most certainly paying too much.
The StdCost right now is a dime. You can get away with less if you're willing to wait for confirmation (which is possible if you're transacting locally with neighbors).
That's what I am getting at. To pervert the old saying, you can't eat a Bitcoin. Presumably what this person wants is some instrument that can be exchanged for, say, 50 kilos of rice. Are Bitcoin and Ethereum really the best such instruments within Venezuela?
