Wallet and coins will be release/distributed after the IPO ?
And the fund will be used for extra features, but the product will works few days after the IPO ?
(I need details because I invested in Exocoin and the product is not launch yet, after months of works...)
Coin is launched already. Core features are working fine right now. You can try out all features ant time using testnet (see OP how to install).
Basically you are investing in 100% functional product. Future updates are mostly cosmetic changes, new design, anti-bloat system, marketing and several concepts (like auctions and serch-engine) - again see OP for updates.
