>> I'm sure MC2/Netcoin's success wouldn't be affected by clones, and I think the devs shouldn't worry about it.
You are sure about it? Why?
...
I can't be sure, but I'm pretty confident. I believe people will be able to differentiate what is the original and what is a cheap clone, and will support the original. Technically, there may not be much difference between Litecoin and *insert random clone here*, but Litecoin is still the one being successful, while all the clones will probably die in the near future.
That's because Litecoin existed for a longer period of time and way before this whole copy craze started. They had the time to build up their reputation so that they solidified their position as number 2.
But if you release Netcoin, guaranteed in a few hours someone will fork it and there won't be a way to ensure the success of Netcoin...Think about it....
