Bitcoin is a medium for making and receiving payments over a network using digital bits and encryption. Cryptocurrency eliminates infrastructure and costs associated with storing physical money, authorizing credit and transferring funds between financial institutions in different countries. Bitcoins decentralized public ledger, known as the blockchain, establishes instant trust between parties with no prior knowledge of each other. Bitcoin can be used to top up mobile wallets (such as Neteller) and debit cards, such as Belize-based Advanced Cash. Bitcoin enables recent immigrants to send money back to their families without incurring hefty international wire transfer fees.”]
