SWF is not targeting the same people as Stake.
Stake might have $1k cash per client, since they target people interested in lowest-fee.
SWF just targets people who think Commsec is too expensive.
So $6.5k is not all that much.

"Investors are more interested in controllable revenue and reoccuring revenue. hoping clients keep cash on the platform is not a high confidence revenue line item"
Is the above not reliable?
Client cash is not going to fall toward zero.
That big peak was probably the start of COVID.
Years ago it was a bit higher, and trended down to $6k, but it shouldn't trend down much more than that (unless they introduced near-free trades, and brought in lots of low-cash clients).
