bitcoin is the first currency to generated on blockchain network. we can use bitcoin for pay our invoices, buy products also transfer to the person we want.
any third person can't access to our funds, this currency powered by a secure network we called as blockchain.
as personally experience transactions speed is not satisfy me and if i don't have to, i prefer to transfer my money from my bank account. PS in large amounts and international money transfer, bitcoin is a better choice.
i think in the future, bitcoin could replace gold.
