Being A Youtuber can make you a good living and other times being a Youtuber may only earn you a few hundred dollars per month.
It depends on how many views your videos on youtube get and what the advertisements pay you.
I only have 10,000 youtube subscribers to my Youtube channel and only earn $300.00 per month so it's not all that great but it does pay my car payment so I'm happy and I enjoy doing the youtube videos and would make and upload the videos whether I was earning money or not.
Some youtubers with millions of subscribers and millions of views earn from $5,000.00 to $10,000.00 per month but takes a lot of hard work to earn that income and you have to be very good at making quality Youtube videos.
