Do your own research!

Try out searching for "lost bitcoins", "stole my money" or "scammers" together with the wallet's name, even if you think the wallet is generally trustworthy. For all the bigger wallets you will find accusations. Make sure you understand why they were made and if you are comfortable with the provider's reaction.

If you find something we should include, you can create an issue or edit this analysis yourself and create a merge request for your changes.

The Analysis 

(Analysis from Android review)

From its Google Play description, we have hints of its custodial nature:

No need to keep private keys, or complicated mnemonic to yourself.

Private keys are under the custody of a third-party.

We searched the website, but there’s nothing about self-custody or private keys. We cannot read the User Agreement as it is only available during install and cannot be copy/pasted then translated. It is written in Korean.

Once you join up and sign in. The app allows you to create several different cryptocurrency wallets. The interface is pretty simple and its sign in integrates with Kakaotalk, a messaging and call app popular in South Korea.

Once you have created your BTC wallet, you can then send BTC to your phone contacts.

This was more specifically detailed in a blog post on medium.

BitBerry is a cryptic wallet developed by Root One Soft, a subsidiary of Dunamu that operates the largest cryptographic exchange in Korea, and Dsion has entered into business agreements with BitBerry. Root One is a wallet made by a subsidiary of Dunamo invested by Kakao. It is excellent in convenience. It is easy to use face ID and fingerprint instead of complicated use of public key and private key of existing password wallet. In less than a minute, you can quickly transfer money between your wallets without any fees.

This app is custodial and therefore not verifiable.


Verdict Explained

This product did not get updated in over a year.

As part of our Methodology, we ask:

Was the product updated during the last year? If not, we tag it Stale! 

Bitcoin wallets are complex products and Bitcoin is a new, advancing technolgy. Projects that don’t get updated in a year are probably not well maintained.

This verdict may not get applied if the provider is active and expresses good reasons for not updating the product.

The product cannot be independently verified. If the provider puts your funds at risk on purpose or by accident, you will probably not know about the issue before people start losing money. If the provider is more criminally inclined he might have collected all the backups of all the wallets, ready to be emptied at the press of a button. The product might have a formidable track record but out of distress or change in management turns out to be evil from some point on, with nobody outside ever knowing before it is too late.
