Change discord bot nickname (discord.py)

I have a simple issue that I'm yet to figure out, how can I change my bot's own nickname, because I want to display information instead of its nickname continuously.

tried this :

await bot.user.edit(username=price)

but this actually changes the username which is not allowed to be done multiple times.

async def status_update():
    while True:
        price = str(get_BTC_price(ws))
        await bot.user.edit(username=price)
        await asyncio.sleep (2)

@bot.event
async def on_ready():
    bot.loop.create_task(status_update())

Thanks
