There have been almost an infinite amount of Bitcoin clones, but I have yet to see a Ripple clone or a Peercoin clone for that matter. I'd include Nextcoin, but I don't think the full source has been released yet.
Is this correct? If so, why not?
Ripple seems the most logical to clone because of the superiority of the code, and all one need do is generate a new genesis and checkpoint etc.
Are there a ton of Bitcoin clones because it has the largest market cap, and all want to get a piece, or does all of the undeserved bad rap that comes with Ripple repel clones? That last logic doesn't hold much water when it comes to Peercoin. Or is it harder to attract miners for Ripple because of the fee structure?
This makes no sense to me. Why haven't the other major coins been cloned into oblivion like Bitcon?
