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).
I don't think bitcoin is equal to dollars. The dollar could be used in the world, governments around the world recognise the value of it, people can use the dollar to buy a lot of goods, but the bitcoin is not accepted by people around the world, the bitcoin to pay only accepted by a few shops
