Does a Twitch account cost anything?

Is a Twitch account free? Please answer I want to point it out

No, the account is free. Just "subscribe" to a creator costs something. But to "follow" a creator is free.

The difference between "follow" and "subscribe" is that when you "follow" a content creator you will only receive a notification if they are streaming or their stream is displayed when the app starts. - With "subscribe" you pay money and usually only have the opportunity to write something in the live stream chat and also have special "emotes" for the chat or other gimmicks.
