[13:43:58] [Server thread/INFO]: [EnjinCraft] Disabling EnjinCraft v1.1.4-spigot

This plugin and Enjin are a waste of time and money. The sync of the wallet in the enjin site never works, i lost many dollars sending enjin coins to the wallet but their system simply does not work.

The plugin does not even work for version 1.16.5. I have been trying to get help in the EnjinCraft discord but no one is responding.

good :v
.

This might be the future of videogames. I'll definitively try it on my server. The blockchain is powerful

Great resource and has a lot of helpful information given in the video for owners to be able to use this on their server.

With the additional benefits for developers as it's a open-source project for additional features to be added.
