If we compare the crypto assets market to the stocks markets in general, can Bitcoin be considerated as the equivalent of the dollar?
In the stock exchage we buy shares with dollars.
In the cryptocurrencies exchanges we buy tokens or coins with bitcoins(and other cryptocurrencies, Litecoins, etc).
Bitcoin has another function , it´s the bridge between virtual and fiat currencies , when people get into crypto they buy bitcoin and with bitcoin they buy altcoins , when they want to get cash they sell altcoins for bitcoin and bitcoin for cash
