It really depends on what type of investor you are. If you're trading very frequently on small amounts, then STAKE is cheaper.

If you're trading less frequently on the same amounts or an amount larger than $3,000, SelfWealth is cheaper. Also, SelfWealth would be cheaper over the long run, especially if your wealth increases and you want to withdraw it.

SelfWealth $9.50 USD trade + one way FX of 60 bps

vs

STAKE $0 USD trade + one way FX of 100 bps*

So yes, plenty of reasons to use SelfWealth over STAKE, including a larger selection of stocks, and the convenience of having everything in one place.

* STAKE charge $0.70 USD on each $100 AUD, so it's closer to 100 bps for their FX.
