Bitunix
- Bitunix pays the same 40% on futures fees and on spot fees.
Phemex
- Phemex grants the same tier on assets or on vePT as well as on volume.
- These thresholds assume API trading stays under 20% of your volume; above that Phemex prices you on a separate Pro ladder, which is not modelled here.

Questions
Which is cheaper, Bitunix or Phemex?
One answer at every volume:
- At every volume: Bitunix is cheaper · $300 vs $390 at $1M
Why does the bigger rebate not always win?
A rebate is a share of the fee. A higher fee can hand back more dollars and still cost you more.
- Bitunix: 40% back on a 0.06% fee → you pay 0.0360%
- Phemex: 35% back on a 0.06% fee → you pay 0.0390%
- What you pay is the fee after the rebate, not the rebate %
Can I use both codes?
Yes.
- They are separate exchanges, so each account gets its own rebate
- Open each one through its own Rakebk link or code
- A code only works on a new account
How are these numbers worked out?
- Every order counted as a taker
- At the fee tier your monthly volume reaches on each exchange's published ladder
- Minus the rebate
- Both ladders are on this page, read from each exchange's own fee page
