Clone Infinite Coin (IFC) and improve with new features. IMO it was and still is one of the better altcoins.
Here's why -
- No premine
- Community is active.
- Plenty of games/support
- Everyone is happy with the large number of coins.
- Value has appreciated more than 30 times what it was worth back in July
- #14 market cap out of 80+ alt's listed on
http://coinmarketcap.com/The sweet spot for total coins is 10-100 billion any more than that and you'll get stuck with second tier trading pairs. For example doge/coin or xpm/coin rather than btc/coin or ltc/coin.
What special features to add? Without much/any experience with these new implements here's a short list.
Colored coins sounds interesting, however I don't personally know how it works.
Name/ID's instead of addresses
And for coin support
IOS/Android wallets at or soon after launch
