    As a technology, crypto does (on paper) solve most problems with FIAT currencies. The problem is as always the people using it. Just like the article linked above, when you have mono/duopolies it can become a problem. In terms of crypto, when people treat(ed) it as regular currency and kept it stored in centralised locations, it makes it easy to take advantage of them.

    Likewise, literacy about a technology starts off low. Just how in the early days of eshopping using a visa/mastercard there were probably many people getting scammed to input their card details in sites they shouldn’t have, there are many people who dont know how to be safe while using crypto today.

    Instead of being bitter to the tech because you or people you know got scammed by being careless with their money, see the positives of the tech and make steps to educate them so it doesnt happen again.

    Oh, Im sorry. If I’m honest I completely forgot. Here it is:

    You will need ffmpeg installed, and I did write it for Linux, so I’m not sure if there are differences for windows. Worst case you need to slightly modify it to work on windows.

    #!/usr/bin/env python3

import requests

    """
    Downloads video chunks from the given base URL and merges them into a single file.

    :param base_url: The URL to the playlist or base directory containing the video chunks.

    If you guys can recommend a fair and open pastebin alternative for me I will upload it there as well and edit this with the link
