Bitcoin Forum

        For Bitcoin, multi-signature technology has undergone extensive testing and is supported by various software. Using electrum software, and both ledger and trezor hardware wallets, (or more different brand hardware wallets, like bitbox, keepkey), you can generate a multisig wallet, 2-of-2, or 3-of-5,...   Each transaction needs all signatures of different brand hardware wallets.  This is a good way to prevent individual wallet companies from doing evil. This is very very safe, and is a true decentralized solution.
        However, Unlike Bitcoin, Ethereum's multi-signature is based on smart contracts, and there have been instances of smart contract vulnerabilities where hackers have stolen tens of millions of dollars. If Genosis safe (Maybe the only software, which supports the Ethereum's multi-signature) leaves a backdoor in the contract or is successfully hacked, then the clients all die. That is, it has a single point of failure, unlike Bitcoin's multiple signatures.Moreover, there is no evidence that Genosis safe is much more reputable than Ledger and trezor. The multi-signature of Genosis safe software, then, does not provide any more security than a single hardware wallet, such as ledger or trezor!
        Another solution is that: Using trezor hardware wallet (the mnemonic word is generated myself by python, then the trezor company will never know it. This prevents a random number seed backdoor for setting mnemonics), and a third-party software in an offline environment, which provides a double-layer security protection(For BTC, the trezor never be connected to network, and the only way to reveal the mnemonic is through the two-dimensional code of trezor's signature displayed by electrum's software). However, I cannot fine a proper software, that support the trezor's signature in offline environment.
        So maybe the best choice for me is: Generate a mnemonic phrase through programming by myself, input it offline into a Trezor wallet, and use the Metamask software to read the Ethereum address offline. After that, store USDC and DAI, and use the wallet only once.

        Final question: Why do I want to store USDC, DAI, USDT? Everyone knows that the price of bitcoin has a cycle, when the price is too high, sell it for USDC and DAI, wait for the price to come down (about 1-1.5 years), and then buy back Bitcoin. A better solution would be to sell the bitcoins and exchange them for dollars or euros, or some other local currency. In my country,  cryptocurrency trading is not legal, it is easy to receive illegal  money on Binance, and bank cards will be frozen.

First of all why do you want to securely store USDT, are you gonna holding for a long period of time? If yes is there any major benefit store USDT without staking it

The secure way that I know is through Hardware Wallet like Ledger. Today Hardware wallet able to save multiple network chain so you dont need to worry about it.

You can store them safely unless you put your stablecoin in DAI. You'll never what could SEC's regulation would approved. There are instances that USDT was frozen in a wallet.

DAI must be the answer although decentralization in ETH network is constantly questioned. Since there possibilities of nightmares to happen just allocate certain percentage of how much to keep on exchanges and on your private wallet.

It's not as complicated as you said. I'd been storing my USDT for several years. I just keep it on my offline computer which is not connected to the internet, i connect it once i need it to send it out from that device.
I just store it on mycrypto wallet(desktop wallet) that can generate a new wallet in offline mode. The main key to store anything safe in your wallet is you must try to protect your wallet from storing it in the device that is always used to connect into the various sites.
The hackers have various ways to steal your money. I just do that and nothing happened with my money till now. It's being stored safely in my offline device.

I don't see neither are good methods to store your USDT. The key is never try to store your wallet in the device that is often in connecting to the various web3 services like defi, nft or anything else.

I think you overcomplicated the vulnerability scenario. With a hardware wallet (as the main wallet) JUST for storing it should be pretty safe if you know what its purpose of such a wallet is.

A tip for interacting with smart contracts is to use another software wallet like metamask on another device with a small balance (do not connect your hardware wallet directly).

I currently only hold Bitcoin, if one day the price is too high, I want to sell it and convert it to USDT. When the price is low, buy back Bitcoin. In this way, my Bitcoin will increase more and more. A single hardware wallet is not safe enough. I live in Asia, and Ledger and Trezor are in Europe. What if they themselves do evil? At least two independent well-known companies must jointly guarantee, that is safe enough. For example, Bitcoin's multi-signature, as well as airgapped wallet + trezor. I haven't found a suitable wallet that supports Trezor in an offline environment.

Although there have been no malicious cases of hardware wallets such as Ledger and Trezor so far. When I saw someone mention: "How can you trust a company in a distant place not to steal your money?" I still don't feel relieved. If there is a storage method on the Ethereum network that is as secure as Bitcoin's multi-signature, it will be foolproof.

In the United States, if you are not concerned about receiving illicit funds, you can directly convert BTC to USD instead of USDT, which is considered safer. In China, there are no legally operating exchanges, and converting to Chinese yuan may involve the risk of receiving illicit funds. It might be better to hold USDT, as it avoids potential involvement with illicit funds.

I'm a bit confused about the issue OP mentioned, USDT storage?

I haven't come across many situations where stablecoins have to be held for long periods of time, and even in the short term it appears to be only a transactional intermediary element in this environment, and for personal use that I'm aware of ( transaction amount of less than $1 million), storing it safely is not difficult, just like you would hold any other type of cryptocurrency. The various incidents in this market are not really new (hackers, CEX bankruptcy, etc.) but it is not a worrying error compared to the whole, imagine billions of hacks $ with a market worth trillions of dollars. So for me, even if I keep USDT on any network, I am quite assured, perhaps if an incident occurs, it is still a mistake from personal management.

Although Ledger and Trezor are extremely secure. However, Ledger and Trezor hardware wallets manage at least hundreds of billions of dollars. How can you ensure they won't act maliciously? How to guarantee absolute security?

You're still the only one who has the seed phrase so "absolute security" depends entirely on you unless you use their feature that lets you back up for recovery purposes. I'm not knowledgeable to discuss the risks involved with that but Trezor and Ledger had been criticized when it was added.

I think Trezor is better for security since it's fully open-source which means there are thousands of outside devs that are checking and watching it.

Agreeing with the perspective that Trezor is safer, if all of Trezor's code and firmware were open source, it would be impossible for any backdoors to exist. By diversifying and using both Trezor and another similar wallet (such as BitBox), the security level increases. However, Trezor is not completely open source, which means it cannot guarantee there is no backdoors.

I heard that Ledger plans to offer a service where users' private keys are split into two parts and uploaded to two different servers for separate storage. If such a service exists, I would not use Ledger anymore. It's important not to fully trust any institution, government (Especially corrupt governments, like mine.), or company.

What am I missing here? Which part isn't and when did they implement that? Their software and firmware are fully open since the beginning from what I know. All their repositories seems public so I would assume everyone could access and review it.

It's crazy how they're changing. I guess they are more into the mainstream users now.

You store USDT offline, and once you connect to the network, you change to a new wallet? That is using a one-time Ethereum wallet, which is similar to my second solution. Using my own generated mnemonic phrase is mainly to prevent wallet companies from leaving backdoors in the random number seeds of mnemonic phrases. You can use trezor's passphrases with at least 15 characters.

You mean DAI is safer than USDT？ Thanks.

If you are referring to storing USDT in a secure wallet, you have two options in that matter: centralized and decentralized exchange, and it can also be in any non-custodial wallet. It just depends on the research you do to keep USDT in your wallet.

You can choose from many, but what I said is that I'm not sure if these are what you're looking for because I can't be sure what you're referring to, to be honest. I'm a bit confused by what you're explaining, because in every network that you are going to use there is usdt like in Erc20, Trc20, Bsc20 and etc.

What and who do you mean by multiple independent authoritative companies? can you give some examples of what you truly mean?


That is truly a bad idea. What makes you think a mnemonic phrase generation that you created by yourself is better and more secure than a popular cryptocurrency wallet whose have been used and managed by a lot of people and it also proved to hold a gigantic amount of funds safely and securely? By doing that would rather increase the risk of losing funds by some means related to the process.

Why do you get into so much trouble? There's no need to overthink it. Just use a hardware wallet that's sufficient. Hardware wallets are very secure and support several cryptocurrency chains. There's no need to worry so much that's fine. Nobody wants to take any risks everyone wants to stay secure. In my opinion, using a hardware wallet would be a better choice.

Where everyone else is thinking about holding Bitcoin or other coins safely, your thinking is a bit different. You are thinking about holding USD instead of holding Bitcoin or other coins like everyone else. From your decision, it seems to me that maybe you don't like to take risks and are content with what you have. Whether to invest or not is entirely up to you, here we discuss how to safely store USD. First we need to select a wallet with more security (Electrum wallet, Mycelium wallet, My etherium wallet). By choosing a wallet with more security, we can easily store USDT in that wallet by making a specific account in that wallet. But we must be careful that no one can know the private or secret information of our wallet only if our USD is safe in our account.

On a cold wallet, or better in cash. And USDT itself is not a stablecoin, USDC is better, there is also decentralized DAI

I thought USDT can be frozen even in your wallet?

So if that be it what is the security in holding the coin in your secured wallet when the developer can still render it useless even in your wallet,  so I wonder what it will feel like having a secured shit,  USDT is best use for trading and if you want to store any coin for long term,  you should store Bitcoin or ethereuem instead.

I think the easiest and best way is to use a non custodial wallet. There are different wallets out there. Like MetaMask, BitKeep Wallet and more. These wallets are safe and can only be managed or controlled by you.

I have re-edited the message description, which should answer your question. thank you.

Thanks, USDC and DAI are better.

On my opinion, mainstream hardware wallets, like ledger, trezor, bitbox, keepkey, are better choices.

So you don't believe in companies like Trezor or Ledger while some companies is like Trezor is open source I dont think there is enough option out there. The best option right now is by you creating new wallet and save your private key on paper or indestructible material like metal and that is. I think it is safe enough or can use multi signature wallet but Personally i never using it

       I prefer Trezor than ledger, because of Trezor is open-source. I trust trezor and ledger. but I don't think it's wise to trust a company completely. In China, some small banks even deliberately run away with customers' deposits. In the United States, Silicon Valley banks collapsed. You can't 100% trust any institution, any government, any company.
        BTC's multi-signatures make it technically absolutely secure. Ethereum's multi-signature, by nature, does not provide any greater security than a single hardware wallet.

Trezor and ledger don't manage your money or keys, that's you. First get a lesson what a noncustodial wallet is.

Of course there is no trust worthy of being given to any company, but in a situation where you have limited knowledge and no other options, then the decision to use it can be based on recommendations or reviews of mostly verified advanced users. There is no guarantee of absolute security in this type of wallet or multi-sig wallet, there is a definite risk especially from the user's side.

I just want to express that Hundreds of billions of dollars are managed through Ledger and Trezor hardware wallets. It's a huge temptation.


 I cannot find a particularly secure way to store Ethereum tokens. This disappoints me. If I have to trust a single company to store Ethereum tokens, I don't consider it truly decentralized. These experiences have solidified my belief in investing only in Bitcoin in the future.


Thanks. I have many hardware wallets, like ledger and trezor.

I am sorry that I do not have enough knowledge.
I ask GhatGPT, and the reply is:
        However, despite the core code of Trezor being open-source, the hardware itself may contain proprietary components or chips that are not fully open. The functionality and code of these proprietary components may not be subject to public scrutiny. This means that even though the core code of Trezor is open-source, it is very difficult to completely ascertain the absence of backdoors on the hardware.

If you can buy a hardware wallet, do it. Trezor is a good option if you can afford its price.
There is no perfect open source wallet that offers you all of these options, but there is a combination of them.
The NEW wallet provides you with the ability to store USDT DAI USDC on the Ethereum and Matic blockchains.
USDT TRC20 can be stored in tron-wallet but I prefer USDT over Matic

Do not take financial advice or it may lead you to lose your money from GhatGPT.

@OP next time if you want to reply more than one user, you need to compile it to one post, don't post in a row because the forum forbid it.

I see many people already answer using hardware wallet e.g. trezor, but you still not trust about it because you can't rely on trezor's company.

To clear your doubt, my answer is none and you need to convert all of your coins into Bitcoin because you're understand if Bitcoin is the only one coin that's very secure to hold due to decentralization, transparent and verifiable.

Storing stablecoins in the hardwallet for the purpose of preserving the value of your profit is good, and seriously as I understand here you already have your prospect about buying a good hard wallet, I don't know if you meant to ask or this is just a marketing purposes. Anyway, I'll go for Trezor this time because of the issue with Ledger, I'm starting to move out my holdings and transferring it to Trezor for my own peace of mind.

Saving your digital assets in USDT or other stable coins will not provide any increase in your investment. If you really don't want to store your assets in crypto, I suggest storing them in the form of real assets such as gold or property. What I can say is that it is best not to keep your assets in FIAT money because their value will continue to decrease from year to year.

Don't. Please do not try to securely store your USDT because that means you are going to trust it way more than you should and that will end up with you believing that it will be something you could hold for a very long time. But we have no concrete proof that USDT is secure itself let alone you secure yours.

It could end up with something that could result with a big loss if you are not careful and I believe that we are going to end up with something that will result with a big return that will not be smart at all. I understand that it is not a simple thing but at the end of the day we are going to end up with a result that should be enjoyable and having USDT for long term will not be enjoyable at all if you do that.

definitely some wallet like trezor, that at least have many measure are the way to go if you want to avoid your money ever being stolen.
I just don't think that there are any other safer way to avoid your money being stolen at this point, generating wallet for paper wallet sometime also seem futile considering that you have the chance of losing access to your wallet if you lost the paper wallet.
so i think if you have hardware wallet which you do, then just stick with it, its by far best solution that you got, the fact that many other also use it means its quite effective.

Staking your stablecoins is also risky, you can't guarantee it is safe. The best example that happened was the Luna Classic (UST) when that stablecoin was depegged, that's the main issue you want to avoid if you are into stablecoin.
Another thing is the platform you are staking, it is centralized, so there could be a lot of ways that the platform could lose your stablecoins.

Trust is the elephant in the room. Does Ledger, Trezor, or multi-signature technology deserve our trust? You seem to be trying to eliminate trust by adding security layers. Can you ever be safe in the cryptocurrency wild west?

Dont even mention Ethereum. I agree; smart contracts are time bombs. Not "if" but "when" they'll fail. How could anyone trust Genosis secure when its reputation is no better than Ledger or Trezor?

Why store in USDC, DAI, and USDT when you can convert to USD and bank it? You state your country bans cryptocurrency trading. Well, theres your sign that maybe, just maybe, the powers that be know something you dont.

I don't store USDC, I farm with it. Why would you just let it sit when you can get around 500% during the Q saving and borrowing incentive program? Even providing liquidity on a dApp like pancakeswap should get you higher returns than storing it in a savings account. Put that money to use or lose your money to inflation!

I live in Asia as well and have no access to a cold storage or a hardware wallet and what I am currently using is a hot wallet called Mycelium I've been using it since 2017 and have no issues or problems with it. You can have Bitcoins store on it and then convert it to stablecoins like USDT when it is needed. It also has support to cold storage if you have one.

By that logic why keep your money in the bank? Government could takeover all of it and consider it as theirs to cover expenses of a crash, which they have done in a few nations. They had one in Cyprus if I am not wrong where they took the money right out of your bank account if it was more than a certain amount, to pay for something, I do not remember what it was.

So all in all we have to realize that it is not going to be easy to fully trust anything, what if you get gold and put it in a bank vault? You may get it stolen, who knows? Or what if you get banknotes and put it in a safe at your house? Could be stolen there too. All in all, if you want to look for the impossible, you are going to find it everywhere you look.

You are absolutely right.

I am also think about it. As a newbie, I have waste too much on junk hardware wallets like Ledger, and other close-source hardware wallets.

Yes, the design and all codes of open-source hardware wallets were verified by many experienced people. I can 100% trust these community supervision.
I wonder that I will buy a bitbox, and then half in bitbox and half in trezor. My ledger will be discarded in near future. There can be no security without supervision.

Simply store it in a private wallet that you don't use for any activity apart from that. Use your other day to day wallet for websites, exchanges and all other your activities .Thats how i have been storing crypto-assets for many years now.

Yes, the safest solution should be simple. I plan to use a 2-of-2 multi-signature wallet (Ledger + Trezor) to manage Bitcoin, and two single-signature wallets with passphrases (Trezor and Keystone) to manage Ethereum and BNB tokens. It can't get any more complicated than that.

Storting USDT or any other coins on the decentralized or centralized exchanges especially CEX is very high risky i think. Because you know CEX can be hacked at any time even Binance also hacked in the several times. Secondly, there are no benefits to hold stable coin for the long time if it will not be staking or farming like that. Another trouble is stable coin be frozen because it’s a decentralized ecosystem.
