There are 2 ways to share the link of your Channel in Telegram, so users can either read your public channel or be requested to join the channel via the join chat link.
If you just share your Channel’s link (Use @YourChannelName inside the Telegram, or Telegram.me/YourChannelName outside the Telegram), users will be able to read the content of your public channel by clicking/tapping on that link and there is a Join button on the bottom of the screen letting them join your channel.
But there is another type of sharing Channel’s link in Telegram, which is called JoinChat Link and asks the user whether he/she want to join a specific channel as soon as clicking the invite link, without showing the content of that channel. In other words, it makes you join the channel in Telegram to read its posts, which is a very good idea to increase the number of your channel’s subscribers.
