Some tips from yours truly:

• Change the text font. It's like you only used the default font of the videomaking software.
• Probably change the music. It sounds too generic, like from those cringey motivational videos.
• Using of stock videos are fine. Everyone uses stock videos. But don't overdo it.
• Not sure about the people here, but I really don't like the portrayal of bitcoin being a physical gold coin. It's just misleading.
