That is true, but exchanges are now integrating BCH, people can now buy BCH with their credit cards.

Most people when they get into BTC, they don't buy 50,000$ worth,but maybe 50$ or 100$ just to try it out.

If the TX fee is 50$, then literally most money is sitting on exchanges, very vulnerable to theft and has no way of participating in the economy. They can't mvoe their money out.

Low fees are imperative for a smooth economy, this means as soon as more exchanges integrate a FIAT<>BCH bridge, as soon will people use BCH for commerce.
