existing altcoin features that are actually valuable to members of the crypto community
to me it would be
fast
secure
payment gateway and accepted by business (great marketing)
no instaming, no ipo, no premine, dev's earn money off of payment gateway (the more the coin is successful the more the dev earns)
superior wallet (most wallets look like something out of windows 95) wallet should include everything, mining, trading, purchasing, accounts, payees, messaging etc etc etc
an app with the above all achievable on an android (no-one likes iphone but i could be wrong)
ohh ohh and mining that is done at one hash rate only (the more hashing you throw at the coin does not matter as it will only accept the one hash rate), so that it is achievable by all. Can be mined on a smart phone and every thing i do in the wallet gets me rewarded with coins
