How to follow a crypto project's changes
A watch follows a subject you have already asked about. Watch buttons under a finished answer offer to follow its subjects; each button's hint reads «Get updates on this in this chat».
The updates have one destination: the chat the watch was made in, also when Telegram is connected. In that chat the updates sit in time order among the answers, each marked with a bell and its own time.
Watches are limited per person; when the limit is reached the site offers to stop one of the watches first. Deleting your data deletes the chats and their watches.
FAQ
Do I need Telegram to receive updates?
No: a watch made on the site belongs to the site chat it was started in, and its updates arrive there — even when Telegram is connected.
How many watches can I keep?
A per-person limit applies; when it is reached the site asks you to stop one of them first.
