How much does Aura Finance cost?

Can you tell me, how much does Aura Finance cost to invest in? I'm considering adding it to my cryptocurrency portfolio, but I want to make sure I have a clear understanding of the financial requirements before I proceed. Is there a minimum investment amount or are there any other associated costs I should be aware of? Additionally, are there any discounts or promotions available for new investors? I'd appreciate any information you can provide to help me make an informed decision.
