Most of the suggestions are using a prominent centralized or closed-source platform. I don't blame that since I do aware most of them have good features and excellent conveniences. Nevertheless, If someone wants to seek a portfolio tracker that truly protects user privacy, I encourage all of you to utilize an open-source solution.
One application that I am aware of is
Rotki. I know that some users who take their own privacy consciously are using this tool to manage their own portfolios. A lot of features(
https://rotki.com/#features) are available to manage anything related to cryptocurrency usage. If anyone considering which app to use, it would not hurt to take a look at this tool.
Saluting your endorsement of open-source whizz-bangs like Rotki for crypto-management. Sure, they've got an edge on privacy versus the central command.
Still, privacy's not a done deal by merely flipping to open-source. Mind, using an open-source wizard doesn't mean you're privacy-proof, especially if digital manners and security steps stay old school.
Rotki, while packed with goodies, raises questions about user-friendliness and ease-of-use. Newbies might wrestle with its tech intricacies. Also, we gotta consider trust: Is the user crew big enough to back its dependability?
Agree, one can not gain privacy by simply switching to FOSS, but one would potentially be able to achieve it one step easier. In this specific case, the user is not utilizing any third-party dependent on the data storage mechanism. It is a fully local application, and the database itself is encrypted. It is certainly better than any other application, within that specific manner.
One that is inadequate is surely the conveniences, as among many other open source apps, sometimes, user-friendliness is lacking. In many cases, they would not be able to compete with other non-open-source solutions.
Regarding development, they have paid option to sustain financially. Also, everyone absolutely can contribute to and maintain the app on their own. The main point, the community and the developer are pretty much still solid to do the updates, as of now.
