How much will BCH tx fees if it reaches a $1 trillion market cap?

I've seen BTC tx fees increasingly grow over the past decade which made me really happy to see BCH rise up (and much more recently Chia/XCH which holds tremendous promise of fulfilling Satoshi's vision but with farming disk space instead of mining GPU). However, BCH's market cap is still just around $22 billion while BTC's is almost $1.2 trillion. What are the anticipated tx fees if BCH was to reach $1 trillion in mcap by the end of this year? I'm trying to figure out whether it can stay true to its vision to be used as digital decentralized cash and whether I should incorporate it into an emerging project.
