How to make a multi-threading bot?

Question

Python

Hey! How can you make a telegram so that the bot does not break when it is used by a large number of people? And then I test the bot at home on two phones, the first user who started / start the bot does everything right, then the second person does / start the program starts to blunt. Give advice on how to fix it

Answer 1

everything that concerns users to store by linking them to each and store data not in memory but on disk (in the database)

Answer 2

asyncio

Answer 3

Libraries are used, or samopis? All libs have multithread support. If the program "begins to be stupid" when the / start button is pressed, the problem is clearly in the code itself
