So, if I understand our Fun on freebitco will became Xfun?
No, XFUN will be the new token on Polygon network.
There's more to come, including XFUN, the new Layer-2 token on Polygon that would create a dual asset deflationary ecosystem with $FUN. Stay tuned!
Or we will have 2 token: Fun and Xfun? And what will happen with locked tokens?
Yes. I believe nothing will change when it comes to 'old' FUN tokens.
