To be fair and accurate - currency conversion does have a fees ..not the txns in the same currency .. credit card charge or cheque book fees are the convenience charges .. but if you buy a coffee with dollars , you DONOT pay a txn fees

..much less you bid a fees and only the highest fees txns makes to confirmation .. lol 🤣

Bitcoin network is an Asset transfer network .. much like the county clerk to register your home deeds .. you transfer the assets ..you pay the fees ..

In fact , every asset is a network .. gold is a network of goldsmiths and miners .. Apple stock is a network of apple shareholders and brokers ..

Network is the Asset ..
