Then where are all those wallets and other features for Digibyte?
All those "new features" your talking about are simply taken from bitcoin core. A big giveaway is "Rebranding to Groestlcoin Core. To reduce confusion between Groestlcoin-the-network and Groestlcoin-the-software we have renamed the reference client to Groestlcoin Core." which as you can see here (https://bitcoin.org/en/release/v0.9.0) is the exact wording of the bitcoin patch notes.
Not to dimish the achievments of the Groestlcoin team but to say that it took more "work" than the digibyte marketplace and digibyte gaming is absurd.
Rather than update the codebase to a more recent version of bitcoin (something that almost any decent coin dev could do), Jared instead spent his time developing useful and unique services centered around the coin itself which is something very very few coins have managed to achieve. Then instead of copying and pasting features from bitcoin we went our own route and decided to preemptively solve a major issue plaguing the bitcoin community at the moment.
If you really take a look at that list of features you'll see that DigiByte has already had alot of them (coin control, OP_RETURN, Strict DER encoding) for quite a while as DigiByte was upgraded to the 0.9x codebase 1+ years ago.
At any rate I won't argue with you any further.
