Such an application is called Blockfolio. But what are the main functions, and is Blockfolio safe to use? Let’s talk about it in the article.

Of the disadvantages, it can be noted that there is no separate account to save the history of your portfolios. Moreover, there is no way to synchronize the entered information. If you change your phone or lose it, you need to enter everything from the very beginning, but the developers have already promised that there will be an update soon.

Analogs of Blockfolio

Unlike CoinMarketCap, which only generates statistics for each individual cryptocurrency, Blockfolio allows you to get rid of unnecessary information and customize your profile to evaluate personal investments.


One of the worthy analogs of this service is the CryptoCompare program. Especially if you need an application to monitor the cryptocurrency portfolio in a desktop version. This website allows investors to evaluate the result of a particular transaction.

It also makes it possible to monitor changes in the profitability of the crypto portfolio, assess profitability, and analyze risks.

This site requires account registration. However, there is an interesting feature here – the site allows you to monitor the fullness of other users’ portfolios, which can be useful for novice investors.


Delta is a very well-known alternative to Blockfolio which has some advantages. There is also a mobile version for various operating systems and a wide selection of crypto assets. Among the advantages are the ability to separately monitor certain coins and the collected portfolio, connect notifications about exchange rates on exchanges, and an advanced paid version with useful functions like the ability to synchronize data with personal devices.


CoinTracking is another useful application for managing a cryptocurrency portfolio. This service is good when working with short-term investments. You can use it online through the official website and mobile versions. The tracker shows various information for instant decision-making about buying or selling coins.

These analogs can be used in conjunction with the Blockfolio application to obtain more accurate information and efficient asset management.

Security question: is Blockfolio safe?

Despite all the transparency of the service, it is impossible to talk about complete security using it. Recently, a cybersecurity specialist from Integer discovered a vulnerability when he decided to check the security of the cryptocurrency tools he used.

Is Blockfolio safe to use

He created a code that connects to the Blockfolio repository on GitHub using a set of constants, including the file name and the key that GitHub uses to grant access to the repositories. 

The application sent requests to closed repositories, and this function downloaded Blockfolio’s frequently asked questions directly from GitHub, saving the company from having to update information inside the application. However, this feature is dangerous because it allows you to access and control the entire Blockfolio storage on GitHub.

However, the key he discovered was still “active and had an OAuth Scope “repo,” which is used to restrict the application’s access to the user account.

Repo, according to GitHub, provides full access to private and public repositories and includes access to read and write code and fixing the state of the storage and the organization’s projects.

The vulnerability has existed for two years. The expert warned Blockfolio about this problem via social networks since the project does not have a reward program for developers who detect such errors.

Blockfolio co-founder and CEO Edward Moncada confirmed that the GitHub access key was mistakenly left in the previous version of the Blockfolio application codebase. When the team received a vulnerability alert, Blockfolio revoked access to the key.

This case only confirms the guesses about the insecurity of the service.


Blockfolio is a more advanced alternative to resources with simple statistics.

This is an application with extensive functionality for a more effective assessment of the assets of an investment portfolio.

The program is free and does not require registration. Using the application, it is effortless to track the status of your assets directly on your smartphone.

However, despite all the advantages, it is worth remembering your own security before downloading the service.
