I'm not familiar with symbolic links yet.
Then it's time to get familiar with it. The most basic command (which cover many use-case) is this
ln -s /path/to/source /path/to/link
For example to link
/mnt/bitcoin to Desktop, you use this command. After executing the command, you should able to see shortcut/link to
bitcoin directory on your Desktop.
ln -s /mnt/bitcoin /home/user/Desktop
If you wish to remove the link, just delete it normally (with
rm or your file manager).
P.S. create new file/directory to try it without risking your important files.
