The Guldencoin block target is 250 seconds not 150 seconds, maybe you should double check your facts before you post.
Obviously it is 250 seconds but it should be 150. You just even quoted the reference I gave you and you obviously didn't bother to look at it : (
https://explorer.guldencoin.com/#/). It is also obvious that Digishield introduced this. It is also obvious that NLG-miners saw their income decrease by 50%. Maybe nobody noticed, being too busy pointing at other coins. I suppose this is just negligence and not a deliberate act to slow down inflation. Your latest commit was on May 13. I suggest you update README.md next time or even better to repair this issue. Right now it seems like the worst example of central manipution of a currency I know of.
The only thing that is obvious is that you are (1) quite confused (2) like to make things up.
