getting addicted to tools or tweaks like this actually puts your privacy at risk indirectly.
It is directly affecting your Privacy. Hell! Think about it. You talk about oranges and they pop up on your YouTube ads all of a sudden. It is not a rumor any more, Google is listening and reading every thing it can, analyzing it and trying to use it to the financial advantage of Google.Forum members would prefer it more if you had provided a safer means of doing this on a spreadsheet rather than making use of google.
It is up to each and every one of us whether we want to maintain a high level of Privacy and Security and if some body chooses not to then so be it. I find Apps that promise to help you track your Cryptocurrency Investment Portfolio very weird and sketchy however. I would not trust one such App unless it is entirely Open Source and legitimately audited.OP should not care about what we prefer or not. OP should care about their own Privacy and safety.
I recently came across some posts that were educating on use of google authenticators which most people think Is safe.
I prefer Authy and other Open Source alternatives. Google Authenticator is a nightmare for me. No backups, owned by Google and more. No thank you, I rather have no 2FA.Nice post though op.but using a live chart like coin market cap will do besides there will be no sharing of private data with a third party.
Not sure what you meant to say here. If you meant to say Coin Market Cap will not share private data with Third Parties, you are wrong.
