Whenever you remix, you take away the opportunity for someone else to take this remix slot.
Sure, one coin can make 100 remixes, but then other coins are stuck at 1 remix.
The average 1 bitcoin volume can only remix 2.4 times.
(this is an old chart from dumplings, it's before Wasabi 2.0, which had a remix ratio of between 10-50 per month)
