oh, that's very easy.
as with other digital currencies, all you need to do is spread-the-idea!
do it by any means at your disposal - show it to friends, discuss, post "social" media - whatever is your preference. if we do it right, as our numbers grow, you will see the value of your DCD grow and grow and grow.
but that's not all!
to make your task even easier, when you acquire your DCD (or later) order also some Deep Cheque Clones (DCCs), at nominal value (+1% of the cost) - those are almost identical to your DCD but of no financial value, you can show them around, even give them away while not losing anything.
