TELEBOT Why doesn't the bot only work on 2 devices?

Question

Python

I wrote a bot in tenge, it monitors the exchange rate of the dollar, bitcoin, etc. I started testing, asked my friends to test too, after 3 minutes the bot stopped responding? What can be done?

if message.chat.type == 'private':

    if message.text == ' Rate dollar ':
      

      bot.send_sticker(message.chat.id, open('sticker/dollar.webp', 'rb'))
      bot.send_message(message.chat.id,' Dollar now: ' + str(cur) + ' ₽ ')
    
    elif message.text == '₿ Rate Bitcoin ₿':
      

      bot.send_sticker(message.chat.id, open('sticker/bitcoin.webp', 'rb'))
      bot.send_message(message.chat.id, 'Bitcoin now: ' + str(bit1))		

    elif message.text == 'Track Bitcoin₿ and Dollar$':

      markupda = types.InlineKeyboardMarkup(row_width=True)
      kn = types.InlineKeyboardButton('❗️ Track off ❗️', callback_data = 'off')
      markupda.add(kn)
      
      bot.send_sticker(message.chat.id, open('sticker/sticker1.webp', 'rb'))

      bot.send_message(message.chat.id, 'I started following course $ and ₿.\n You will receive messages every hour  \n                 Dollar now: ' + str(cur) + ' ₽ \n            Bitcoin now: ' + str(bit1) + ' ₽ ', reply_markup=markupda )

      xt()
      
      while True:
        
        if rate == False:	
          break
        
        #parsing old
        #dollar
        full_page1 = requests.get(url, headers = headers)

        currency1 = convert1[0].text.replace(',','.')
        cur1 = float(currency1)

Answer 1

Look... in short:
you are not writing a bot, not a dollar parser... You are writing a program first of all! And the time.sleep(120) command stops the ALL program for 120 seconds
. And the while True command: Loops the ALL program in one place and whoever clicked it first muted it, but the program will not crash and will not give an error because it works! just not right. These two lines must be removed completely, and with this, the entire logic of the program must be rewritten ...

Answer 2

what is rate variable? why does it not participate in the body of the loop in any way, except in the condition for stopping? Is it sure it doesn't hang in the loop?
