Btc in number of transactions loses comparing to fiat. Somene may see it as a downside (noone is paying with it). But is it so? According to Gresham's law, people tends to pay with money with lower inside value. This law takes in count only in case where two currencies are available. For this, El Salvador is a perfect example. According to people who were in Salvador,, btc is rearly used for payments. Of course there are technical issues connected with this situation, but as bitcoin is increasing on its value, the law takes into account.
What do you think about it?
