A first, a pioneer is always most important because it makes a milestone, sets up a new standard, new direction, new growth of adoption.
El Salvador is a first country which makes Bitcoin as legal tender. Fiji even makes a same thing, effect should be smaller. Because there is a first nation made it. In addition, in bear market, effects would be smaller too.
At the end, Fiji did not announce that they are planning to do it. The article does not reveal that plan.
I want to say that when Bitcoin meets politics, Bitcoin becomes a tool used by the government to control the country. Is Bitcoin still pure? If it is perfectly integrated, is Bitcoin under strict supervision? My point is: Anyone and any country can use Bitcoin, but it is the users who need to be regulated, not Bitcoin itself. All in all, this is good news.
