but there's hardly much point in forking unless one can improve it? otherwise we'll just end up with another copy coin
If one is looking to create a coin that has a purpose behind it, then it's not really just a copy coin for the sake of making a copy coin.
Some folks have ideas for what they want a coin to do for a particular group of people, a cause, or some other real reason...
Like me, I am looking to clone a coin to apply to a particular crypto-ignored community, that can help the members of that community to do what they do, and grow their skills and abilities, as well as monetize their skills by helping others.
Not everyone wants to make a shitcoin or exit-scam.
