Google is the best tools to trade Bitcoin anonymously - only search the way to find the Google Private Platform and you can use it without reaving your IP or Phone numbers or Email address connected to your ID.
Is google not having a central server, is google not centralized, why should we now see the best means to go with privacy and still choose otherwise, are you telling that the blockchain technology is not secured enough for the privacy required by every user or we should have an alternative with a centralized entity, google is never a better option to blockchain and even the government and other technology researchers and developers attest to this fact, so why bothering on something that is not it, saving your passwords or private keys on googles has no complete privacy on you.
