MaiCoin - Buy Bitcoin & CryptoLatest release: 6.0.0 ( 2nd November 2022 ) 🔍 Last analysed 1st October 2021 . Custodial: The provider holds the keys
As the provider of this product holds the keys, verifiability of the product is not relevant to the security of the funds!
As part of our Methodology, we ask:
Is the product self-custodial?If the answer is "no", we mark it as "Custodial: The provider holds the keys".
A custodial service is a service where the funds are held by a third party like the provider. The custodial service can at any point steal all the funds of all the users at their discretion. Our investigations stop there.
Some services might claim their setup is super secure, that they don’t actually have access to the funds, or that the access is shared between multiple parties. For our evaluation of it being a wallet, these details are irrelevant. They might be a trustworthy Bitcoin bank and they might be a better fit for certain users than being your own bank but our investigation still stops there as we are only interested in wallets.
Products that claim to be non-custodial but feature custodial accounts without very clearly marking those as custodial are also considered “custodial” as a whole to avoid misguiding users that follow our assessment.
This verdict means that the provider might or might not publish source code and maybe it is even possible to reproduce the build from the source code but as it is custodial, the provider already has control over the funds, so it is not a wallet where you would be in exclusive control of your funds.
We have to acknowledge that a huge majority of Bitcoiners are currently using custodial Bitcoin banks. If you do, please:
- Do your own research if the provider is trust-worthy!
- Check if you know at least enough about them so you can sue them when you have to!
- Check if the provider is under a jurisdiction that will allow them to release your funds when you need them?
- Check if the provider is taking security measures proportional to the amount of funds secured? If they have a million users and don’t use cold storage, that hot wallet is a million times more valuable for hackers to attack. A million times more effort will be taken by hackers to infiltrate their security systems.

Please help us spread the word discussing the risks of centralized custodians with MaiCoin - Buy Bitcoin & Crypto via their Twitter!
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.
The Analysis ¶
This is from the Google Play description:
Securely store Bitcoin, Ethereum, Bitcoin Cash, Litecoin and more in your MAX wallet for free. Your assets are distributed and secured in hot, warm and cold storage. Wallets are guarded with the multi-signature scheme to provide the highest level of protection.
This is a good indication that this is a custodial wallet.
Can I download a copy of my private key?
MAX does not provide a copy of the private key. If you are concerned about the safety of your digital assets, we recommend that you store your assets in cold storage or a hardware wallet.
Security is our number one concern, therefore, we have partnered with KGI Trust to manage customers’ NTD funds. A majority of digital assets are held offline in secure cold storage locations. Customers can be assured that their custodial will be safe and accessible.
As the keys are on the side of the providers that means this app is custodial and thus not verifiable.
