Will the silver backed token be tradeable as a regular Ethereum token that could be listed on EtherDelta for example or will it have to be bought and sold directly through the link platform?
Yes as you can see in our last posted above we talk about a secondary Token called LNKS with price pegged to silver.
Regarding your questions, Token will be available for trading at several exchanges not only Link Platform, it won't be exclusive of
Silverlink.io, the platform will also act as failsafe for controlling Token supply by leaving 'audits' entirely public this means anyone can enter the platform and audit supply versus certificates, buying directly from us and reedeming Tokens for real 0.999 silver bullion; exclusive features of Link Platform.
