You should have a look at syscoin if you like Gulden. In 2019 they reduced their block reward and added a 5% reward reduction annually.
Master nodes get 75% of the reward and miners 25%. They have a governance system where longer term masternodes get rewarded more.
I sold my Gulden for syscoin in 2020 and the coin has performed well in comparison. Gulden is still a good coin but without a reward reduction in the future after the devs increased the rewards by 80%, it left me hesitant to continue on and so far it looks like I made a good decision.
I invested in syscoin since early 2019, legend team. One in a million, they have achieved funding without having to resort to using a premine or mint funding with each block while still getting the coin listed onto multiple exchanges. They didn't expect the community or investors to do this. they realize the people that invest in their coin have jobs and other careers that they can't give the time needed where I get the impression the Gulden developers think the community is available 24/7 to make decisions and be responsible for the coins future while they take half the reward as funding.
The CMC rankings tells the story, syscoin deserve the top 300 ranking they have and more!
Also what's up with the gulden developers creating a new blockchain?
