Do not make a simple clone of a coin. The last few weeks have been a torrent of litecoin clones with a few parameter tweaks. These are not good coins in and of themselves and they are detrimental to the altcoin community as a whole.
So don't do it. If you think that you have a $250 million market to tap into, do it with litecoin or one of the recently released shitcoins.
It would be branded for a specific industry, and wouldn't be meant to compete with other cryptos like LTC etc.
This wouldn't be a coin to trade on exchanges, but to trade between people for goods within said industry. Its purpose would also be to educate younger kids about BTC and crypto currencies in general.
