Can I remove the initial bitcoin folder after installing its binaries to /usr/local/bin? I know this's kinda a noob question, but I really want to be sure I'm not making a mistake.
I want to install Bitcoin Core GUI on my Linux by the following steps:

Download bitcoin-0.20.1-x86_64-linux-gnu.tar.gz into the Downloads folder
Extract it tar xzf bitcoin-0.20.1-x86_64-linux-gnu.tar.gz
Copy binaries into the /usr/local/bin: sudo install -m 0755 -o root -g root -t /usr/local/bin ~/Downloads/bitcoin-0.20.1/bin/*

Each step is exact the same as described here: https://bitcoin.org/en/full-node#linux-instructions
The question is: Can I now remove the extracted ~/Downloads/bitcoin-0.20.1 folder after installing the contents of its bin subdirectory into the /usr/local/bin?
Is it enough to have only binaries into the /usr/local/bin to run the program?
Yes, after you've checked if bitcoin is properly &quot;installed&quot; by checking its version you can remove the ~/Downloads/bitcoin-0.20.1. Be sure to double-check the processes and be careful before putting funds in without backup.
