Whatever takes place with Gulden, the gulden community who contributed to development since 2014 will also take credit for florins success. Most of this contributing community invested in florin and through florin are finally rewarded financially.
I can't say why Gulden is not successful in value when it should be in the top 100, some speculation is a rebranding is needed to get more international users, the name might scare off international contribution.

Gulden is also the last remaining country coin, the other +20 coins are dead long ago, lots of credit must be given to the Gulden team for sticking it out this long and give them a virtual clap for there work having success in another coin.

My suggestion, instead of complaining on this forum, go onto the Gulden slack and post in the GAB channel your ideas.

Florin also has a growing community and it's own slack, if you already have an account on the Gulden slack you can join the florin channel.

Gulden will play a part in the book of Florin, see you soon on slack.
