There are no fixed limits on Credit Lines — neither on the number of Credit Lines you can open, nor on the total upper amount you can borrow. The minimum amount to apply for a Credit Line is equivalent to 100 EUR. The only requirement is to provide sufficient collateral.
This means you are free to open multiple Credit Lines at the same time and choose the size that best fits your needs — from smaller everyday liquidity to larger amounts for new investments.
👉 In short: as long as your collateral covers it, you can borrow as much as you need, without restrictions.
