Kubixcoin

This is my first plugin here. It was made in POLISH-VERSION
WARNING. PLUGIN DOESNT WORK WITHOUT VAULT AND ESSENTIALS.
This is version 6.0. and here is guide how to use it.
When u load up the plugin there will be 8 Commands:
For players:
/imkc - how many Kubixcoins you have
./kc - shows main gui of plugin
./kct - is maid for ops to predict the price of Kubixcoin
./dajkc - is for giving other people your Kubixcoin's. For example:

./kod that if u write some numbers maybe JUST maybe u will be blessed with some kubixcoins.
