I have compared Gulden to a lot of coins at the same marketcap. At the time I am writing this up both Gulden and Worldcoin are $864k.
Lets compare the 2.
Codebase:
Gulden on 0.11 Codebase
Worldcoin < 0.10 Codebase
Gulden far ahead with keeping updated.
Mobile Apps:
Gulden: both iOS and Android
Worldcoin: Android
Gulden wins in catering for both and the quality of the Android wallet is far superior. Usability for the Gulden wallets is increased due to bitcoin payments.
Exchanges:
Gulden: Bittrex, Nocks.co, Litebit.eu, Bleutrade, Yobit
Worldcoin: BTC38, Poloniex, Jubi, BTER, Cryptopia, Bleutrade, Cryptomic, Bittylicious
Worldcoins wins here with the amount of available exchanges to purchase from.
Roadmap:
https://developer.gulden.com/roadmap/https://worldcoin.global/worldcoin-roadmap/I could not get the worldcoin roadmap to load, will reserve judgement.
QT wallets:
Gulden: Install was quick and the sync much faster then most alternatives I have tried. The wallet itself is unique looking and very basic, not as good as the mobile wallets.
Worldcoin: Frustratingly slow to complete the install process after the initial 16mb download, initial sync was really slow but nothing worse then other coins.
The wallet itself has a lot more effort put into it and a lot more options on screen compared to the Gulden wallet.
Worldcoin wins here because of the effort they put into the QT wallet, it's a complete revamp of the general bitcoin QT.
The Gulden wallet is simple and performs exceptionally well but lacking in features.
Rewards:
Gulden 100 reward until 1.68 billion total coins, 10% premine.
Worldcoin rewards reduce every month by 1% and will have a total of 265,420,800, the current supply is 106,871,346 and no premine.
Worldcoins wins for early adopters where Gulden will be able to attract new users with a fairer reward cycle. No premine for worldcoin makes it the overall winner.
Summary:
Should Gulden deliver on it's roadmap I can't see why this is not a good investment, I noticed this coin about 6 months ago and it's my favourite alternative to bitcoin. They still have work to do to become a legitimate contender for the top 20 spot and this can only occur with blockchain innovation.Their Prime project will be the key to unlock this?
