Do cryptocurrency exchanges generally charge more for the exchange from FIAT money to Cryptocurrency than they do when
trading cryptocurrency for cryptocurrency?
For example, Independent reserve charges .5% when buying crypto with FIAT. But is it generally the same again if I buy
say Altcoin with Bitcoin?
I think that fee is for their service. For fiat to cryptos, this mean your invest/exchange your fiat to cryptocurrency, there's some fee for service.
But for more, if you trade from cryptos to another cryptos currency, it's call Cryptocoins trading, and yes, there is need some fee to serve for trade.
Actually, fee for trade is cheap than fee for invest.
