Development was slow to start with Gulden but it's not slow anymore, I don't know any coin that releases faster. It was first coin to do 0.13 code base update along with 9 other innovative features in one release. No coin is faster then the current development Gulden has going. I did have a look at GRS during the 51% attack scandal and all i see is copying everything bitcoin does, no innovation like Gulden has. I do agree GRS does copy bitcoin code faster then most other coins.
You don't know any coin that releases faster? Perhaps you don't know other coins?
Bitcoin and Dash delivers much more releases than Gulden. Gulden is in the top 5 of fast releasers but it isn't the fastest.
AFAIK they did 5 innovative features:
1. HD desktop wallet with mnemonic (recovery phrase) support
2. Fully integrated accounts within wallet physical seperation between accounts
3. New HD Link feature
4. Bitcoin and IBAN
5. In app purchase
These are not innovative:
1. Next Generation desktop wallet (just an overhaul of the gui, any coin can change gui)
2. Local currency (many wallets have this already)
3. Update of our underlying codebase (many coins have this already)
4. Updated mobile apps (just an update, nothing innovative)
5. DELTA. This annoys me the most. When you create a cryptocoin, then the solid base should be good. Gulden is almost 3 years old still struggling to achieve the blocktime it specified 3 years ago. All other coins have blocktime as coded. Gulden is one of the few coins still struggling to get the blocktime that it adverstised. I call bullshit that multipool is to blame. Get your shit straight, Delta is just a hype thing to camouflage that they can't sort the blocktime. If the blocktime was ok, there would be far more dumping because more coins would be mined.
I don't agree that no coins are faster than gulden with releases. I will not mention one, but open your eyes. There are coins out there that releases every month.
I also don't agree that Gulden is innovative as you say. It is a clone of Litecoin and later rebased to Bitcoin.
What is this Groestl thing you guys are talking about?
Sorry i have bought ALOT of Gulden and the price is depressing me. I dont blame the developers or anybody but myself. But i hate it when people are following a coin like sheep and not seeing the truth.
