    try using string instead of keyboard button:

    def start(bot, update):
 keyboard = [["USD", "EUR"]]
 reply_markup = telegram.ReplyKeyboardMarkup(keyboard)
 chat_id = update.message.chat_id
 bot.send_message(chat_id=chat_id, text='please choose USD or EUR', reply_markup = reply_markup)

def main(): 
 updater = Updater('my token')
 dp = updater.dispatcher
 dp.add_handler(CommandHandler('start', start))
 updater.start_polling()
 updater.idle()

main()

    Add logging, so you’ll be able to see if there are any errors or response with error there.

    import logging

logger = logging.getLogger(__name__)
logging.basicConfig(level=logging.DEBUG)
