You can pay for the investment in any way that you and your counter-party feel comfortable with but most people choose to use money in their Abundance account. You can deposit money to your account and ask Abundance to make the transfer of money to the seller at the same time as you inform Abundance about a concluded trade. Read this article to learn how to make a deposit.
Alternative methods of payment might include PayPal, bank transfer or cheque. If you make payment using a method other than your Abundance account please remember to record proof of payment as we will need to see evidence before we record the transfer of any investments.
