hello @joelagbo,
for a couple of years we Venezuelans have understood how this technology works and also its uses in real life, although the government of El Salvador put these coins as legal tender in Venezuela is used at another level, the reason is that the coins and this technology made the difference between prospering in a country plunged by inflation and having to migrate because of poor living conditions, for Venezuelans the coins are more desired or used than fiat money.
