It has been more than two years since El Salvador adopted Bitcoin as legal tender, so that Bitcoin is considered a substitute for fiat money (USD). Currently, the El Salvador government is implementing the Lightning Network as the basis for a very cheap and fast Bitcoin transaction network. The government also recommends that people use the Strike wallet and Bitcoin Beach wallet. Using the Lightning Network as a layer 2 blockchain, it can easily be used as a transaction medium for either selling or buying goods. It can also be used to send money abroad at a cheaper cost if we compare it to Western Union.
