You are missing the point. This even is not about these islanders starting to use Bitcoin, it s all about the event and positive marketing effect of that event. People in the rest of the world hear about, people read about it, people get wallets, buy Bitcoin, use Bitcoin. To put it differently, it adds up to general BTC acceptance and we need a lot more of that.
Ohhh, so this isn't about the 70,000 Dominicans? We're just exploiting them for a marketing gimmick?
Phew, glad we got that cleared up. I thought there might be some ill intentions here or something...
