This is certainly a challenge. LatAm compares to Eastern Asia or Eastern Europe, in that a bottom-up  adoption driven by currency devaluation meets a top down adoption from institutions offering services. 

Adoption is also driven by a high volume of remittances flowing from high income countries to the region. 

So, they’re ahead of the curve in terms of retail use and value transacted. 

However, they like their stablecoins on a CEX much more than a cold storing maxi does. I mean, USDT on a CEX looks pretty stable and convenient, compared to the Argentine peso in a bank account.

So the challenge will be the Bitcoin part. To convince a region, battered by volatility, for a store of value that is more volatile than what they currently use… 

 You have obviously thought much more deeply about this than I have, but is it a two step game?  

i.e.  - Step 1: Build the farm to table supply chain using a mix of digital payment methods (incl. stablecoins), 

Step 2: Eventually (possibly over 10+ Y) as Bitcoin adoption / fiat price inevitably increases and volatility declines, participants in the supply chain naturally choose to hold BTC vs. Stablecoins?    

 I mean, the value has to be there for a transaction to take place. So, the farm to consumer logistics come first. 
We’ve done it farm to restaurant in the U.S., and we’ve seen it done in Switzerland farm to consumer.
Both projects are good ol’ Online Shopping with TradFi payments, email communication and stuff.
The Lightning Network and Nostr are so potent, I would love to see the whole tech built around them. 
It’s just too good to pass it up…
