These coin/porfolio trackers are a privacy nightmare. You're basically telling some stranger your detailed crypto finances, and it's unknown how your data may be used.

One of the golden rules in crypto is to never disclose your holdings to anyone on the internet, yet people are using these apps without a second thought!

Why is that a golden rule? Genuine curiosity.

I believe people say that because by announcing your digital assets you are making yourself a target and raising the opportunity benefit of compromising your computer and/or web accounts.

That's a great point. Imagine if one of these sites got hacked. A hacker could literally walk away with a list of emails, each exchange on which that person has an account, and a list of assets. Time to sort by most valuable account, and go spear phishing...

That's why in Trivial.co we all things client-side only, with the data never touching the servers - that's true for your accounts, but also for stuff like tokens that you watch, and so on.

I hope more startups picked up this way.
