Supercoin has the attributes which are in vogue at present. It has always been surprisingly fast and smooth. I don't know if there is something special in the code... It could be used like Dash, or even Monero.

Better distribution comes from getting noticed by users and to some extent speculators..To be noticed it has to have trading volume and price. To get those a listing on a bigger exchange is needed. A stepping stone to that is a smaller exchange, and all the coding needs to be in place and working first..

So there is no short-cut, just patience and due care. Promotion is not effective until there is a liquid market.

The good news is that the network is sound and has fair support from staking.
