Since you can change your channel name any time you want you can take whatever you want. My channel name is mineversal studios cus that is not original and i own the rights to own it cus none have ever used anything with versal in it.. plot twist got 300000 views on my video.

Make sure you use correct grammar in your username, and don't put "xX" in your name. That usually makes me unsubscribe/not subscribe their channel, even if their videos are good.

No. Just no. Placing xX in your username sounds dumb.

For a good catchy username, it (preferably) needs to be short. For example, a YouTuber who might have the username

Kerbz

(thanks for that example Drasdafy ) will be easier to remember than someone with a long username like SupremeMinecrafterFTW13243.

To further increase the catchiness/awesomeness of your YouTube channel name, try making it related to what you do on your channel. This is a good tip, especially for people who quite don't know your channel's content yet.

But to sum it all up, make it original and catchy. As Phantomic said, don't use the template of 'DoesMinecraft'. Since Sky started his channel and grew more popular, loads of users have been using that template. Try mashing two of your favourite things together as a LAST RESORT.

My YT channel is LogitechNacho. The 'Logitech' part came from when I got my first headset, which was a Logitech make. The 'Nacho' part came from my liking of nachos

Lol it's actually Gameachu now, I changed it yesterday from editing this post

Good username?
Someone

Something original. But don't use something like (someone)playsMinecraft. Too many people use it and it's not really unique.
