All clear. Many thanks

Ok that's clear thank you.

So if I have have 300$ available and I want to buy Bitcoins for 300$. I would rather not use leverage and put all my 300$, rather than putting only 100$ with margin at leverage 1:3. Right? Because as long as taker/maker fees are concerned, both actions are equivalent, but with leverage, I would also pay interest fees. So leverage ends up being more expensive.

As far as I understand, the only two situations where margin makes sense, is 1) I want more buying power than what I have available, 2) I predict a Bitcoin drop and would like to sell but I have no Bitcoins.

Hi,

I can't figure out how margin maker/taker fees work.

Say I have 100$ on my margin account and want to trade Bitcoins. I use all my available dollars (100$) to open a long position, with leverage 1:3, with a market order. According to the leverage 1:3, I now have an open position of 300$. This amount can be divided in two parts, 100$ comes from my money, the collateral, and 200$ comes from a loan from the broker.

Now, suppose the taker fee is 0.2%. But 0.2% of what?? On my 100$, or on the total 300$ that include the loan?

Many thanks.
