Add new Stock: bitcoin

Hi,

i tried to use other stocks but it doesn’t work.
Example: https://finance.google.com/finance?q=BTC
i added BTC, but i didn’t see anything happen.
Could you check it.

I also tried to use new url.
example :https://finance.google.com/finance?q=NASDAQ:ARKR
added NASDAQ:ARKR stock instead of. But it doesn’t works too

Best Regards,
Quoc
