how to make transactions?

think spot. you take a loan of for example 10k$ secured by your deposit for the price difference. this means that you treat your 1k as collateral for the loan in the terms of the transaction (liquidation or profit).

you probably don't know how to manage the amounts you borrow, so treat it as terra incognita. learn to manage this 10k thanks to margin. this is not a lottery. you can really win here
