Dogecoin is just Litecoin with some of the parameters changed and the logo replaced with the Shiba Inu from the Doge meme.  As of this moment, it has a market cap of over 29 million US dollars.  As long as Execoin's developer(s) are following the open source license(s) and making their own source available, it doesn't matter how much or how little they change.

If the worst thing you can say about Execoin is that it's not original or revolutionary enough, then fine, don't use it and don't let the door hit you on the way out.  The altcoin market is full of crap that has been abandoned by developers, blatant scams, premine/instamined garbage and don't even get me started with all the Proof of Stake coins that are just thinly-veiled Ponzi schemes.

Please take your bleeding heart FUD to a coin deserving of it.  For example: VRC mined all of its 26 million coins in 7 days.  DRK was designed so that the block reward would absolutely plummet once the coin reached a certain amount of hashrate and the 1000 coin requirement to be a masternode is just a clever scheme to create buying pressure.  POT has been on the rise lately and it's another "copypasta" LTC clone with the only innovation being their business plan of "Dude, legal pot shops might take this coin some day cause man, there's no way you'd ever use any other cryptocoin to buy your pot!"

EXE is one of the few coins that isn't out to screw over miners or investors and the developers clearly aren't getting rich off this coin.  It's not built on the false hope that maybe someday it will be fully anonymous if the stars align correctly, will save the economy of Crackalackastan or uses a celebrity's likeness without actually having their endorsement.  Execoin is just an easy, fast decentralized way of sending money with a lot of potential if people would just give it a chance.
