If you look at traditional instruments of economy and their interest rates then this 9% will justifies itself. We are entering in an era of blockchain and investing in reliable project or asset for 9% of interest without doing anything is very good. Big investors want state of peace in their mind and for them this is very good rate to attract them in my opinion.
But the 9% are no guarantee, it is a number dictated by the market or do I misunderstand that?
Works like this, you buy a Populous Gold Crypto Coin. You will buy it for 9% less than market price.
If Gold is at 1090usd you will pay only 1000usd as example.
After 12 months you get the actual price of one Gold Coin back* on you Populous Account or you can decide to take delivery of one physical once of Gold.
Its an ERC 1155 compatible crypto coin you can put it on your wallet(needs to support ERC 1155!) or leave on populous platform. With the new Populous Exchange "PDEX" (to be open in some months) you can also sell your Gold-Token if needed earlier.
*I am not sure about it, I heared but this should be confirmed from Populous (in there gold-buy-contract) that there is some protection build in. Would mean you get always at minimum the usd price back that you bought the Gold tokern for. Which is for my understanding, if this is true, the ultimate buyer protection against loss with this Investment.
