The short answer: yes, as no investment is 100% safe. It is illegal for anyone to claim an investment is guaranteed, or a "sure thing".
Money invested in Worthy bonds is not FDIC insured, since that only applies to bank accounts, and we are not a bank.
The Bonds are a general obligation of Worthy Peer Capital, Inc., backed by its portfolio of loans to growing businesses. Worthy is the lien-holder on collateral equal to our participation in the loans so in the case of any borrower default, Worthy would liquidate the collateral, which in our case is inventory, to pay off the bond holders.
