I like the concept! The investors who help the Synapsecoin platform development will receive the % of the profits made by the platform, it's a fair deal!
They plan to spend 50% on marketing, that's a smart choice for the future development! Such platform can't do well without a massive advertising, at least in the beginning.
What do you plan to do with the marketing? There are plenty of other wallets around. Even if you got a better product, you got to get the attention first.
