Guys, I am new to this and really want to invest some. So if the margin is 2:1, it means I can place 20 BTC onsite, and 10 BTC offsite right? Let say the current Bank Roll is 3000 BTC, I will get margin call at 1000 BTC or -2000 BTC profit, right?

So let assume today profit is 100 BTC, so I will get 100*(30/3000) = 1BTC, right? (I understand that the commission is temporary 0% by now, but may change later)

In addition, I need to deposit first via CASHIER and then go to BANK ROLL to invest, right?

Thank you so much!
