I already apologize for being unable to do the math myself.

I need help to figure out leverage trading with btc.

For the sake of the argument I own an account with Kraken of $10.000,00
The bitcoin price is also $10.000,00
I want to trade with 5x leverage.
So how do I calculate the maximum I can buy bitcoin for in order to trade with a 5x leverage.

I understand that if I buy bitcoin for exactly 10k I have no equity left, if the price moves against me.
Basically I cant figure out the margin requirements for a trade.
Say, I want to buy $6000 worth of bitcoin, with 5x leverage, so I am moving $30k bitcoin, but how much money, or equity must I keep on my account as margin requirements?

Please someone help me here.
