Look at this chart: https://bitinfocharts.com/comparison/transactionfees-btc-xmr.html#3m
The average transaction fee using Monero is already over $10USD (shooting up from $7USD just yesterday), and this is with a fraction of the transactions occurring on the bitcoin network. If customers, markets and vendors stampede over to XMR, then fees will end up just as high or even higher than BTC in the medium term.
hey man you can't just come in here and talk bad about monero in the middle of the circlejerk
