Web3.0時代你一定要知道的熱錢包

Hello everyone, I'm Terry. I have shared the importance of cold wallets in previous videos. I have always put my long-term investment in encrypted currency in Ledger's cold wallet. The advantage of a cold wallet is that it is completely offline. The risk of being hacked is basically zero.

Some people on the internet say that their cold wallet assets suddenly disappeared out of the blue. Most of them are because of human error. Like some netizens have asked that if Ledger is closed, will your assets be lost? The answer is of course not. Because what you store in your cold wallet is not your encrypted currency assets, but the private key to the assets. Then when you first created this cold wallet, the address you wrote down

you can restore your personal medicine at any time and any place. You can restore your personal medicine at any time and any place. If your cold wallet machine breaks down. But there is a disadvantage of a cold wallet. If you want to make a transaction or if you want to transfer money back and forth, it will be very troublesome for the money you use often.

The cold wallet is more like putting your money in the bank's bankbook Its purpose is to make a long-term preservation As for our short-term, if you want to use funds Many people will put the encrypted currency on the exchange Like I have some funds in the exchange right now It will be more convenient if I want to enter the field at any time And for example, if I want to transfer money to someone else today Or if someone wants to transfer money to me It's really convenient to transfer from the exchange

As for the risk of the exchange, everyone knows it, it's the risk of the platform. If today the exchange is closed or it is harmed, like the previous FTX, then your assets may not be able to be returned. Of course, it is also possible to get it back, but it takes a very long legal process. Then they will calculate the assets of the exchange.

and see how much is left in the end and then return it to these users. Because the principle of the exchange is that you transfer assets to their wallet and then they give you a balance on this app. This balance is just a trust relationship between users and them. Your real assets are actually in the wallet of the exchange.

you don't have the real definition of these assets. It's just that the exchange tells you that you can take these assets from them. So your right to have assets depends on the promise of the exchange. Between the cold wallet and the exchange, there has always been a more appropriate solution, which is the Web3 wallet.

This is also what I want to introduce to you in this video today. The biggest advantage of Web3 wallets is that you have full control of your private key. Its principle is very similar to the cold wallet. You will have a set of notes When you create a Web3 wallet, you also have to copy this set of notes and write them on paper. This set of notes can help you restore your private key. On the Web3 wallet, your private key is relatively safe.

For example, if you use Metamask, it stores your private key in your local storage. Then use the password to encrypt. Or Biget Wallet stores your private key in your phone, like the iOS keychain. Then your private key will only be used locally to sign a transaction, and will not leave your phone or computer. You may think that this is different from a cold wallet. First of all, Web3 wallets are basically free.

It is a pure software wallet The biggest advantage at the moment is that it can be directly linked to the Web3 application Whether it's GameFi or DeX Or you want to transfer money to others, it's very convenient And the Web3 wallet doesn't have the so-called platform risk Of course it has its corresponding risks For example, your user's end is hacked Or you are authorized to some malicious websites

Then it's like you lost your bankbook But Web3 wallet is the trend of the future Because most of the daily transactions Still need a hot wallet to complete Will be much more convenient And then Dapp and decentralized exchanges Will be more and more popular If you want to connect to Web3 applications You must have a Web3 wallet This is also a service that most exchanges cannot provide

I have a picture here to summarize the difference between Web3 wallet and cold wallet. The interaction with DApp, such as decentralized exchanges, requires Web3 wallet. I will show you how to use it later. Very simple. The security of Web3 wallet is relatively high. Of course, it is not as high as a cold wallet. Because the cold wallet is in a state of complete offline. Web3 wallet is a kind of hot wallet. Because your phone and computer are connected to the network.

The convenience of transactions is also the main reason why everyone uses Web3 wallets. In addition, Web3 wallets usually support multi-chain functions. I think this should be the biggest advantage You can do cross-chain asset exchange on it. If you want to buy some relatively cold or currency that has not been listed by the exchange, then you must use Web3 wallets.

For example, the Thales I bought before is a coin on the Solana chain, and the exchange hasn't been listed yet. So I transferred my USDT from the exchange to my Big Ed Wallet Web3 wallet through the Solana chain. After transferring, I can directly do the swap. The reason for the swap is that Big Ed Wallet Web3 wallet has a combination with most of the DEX.

So they will help me find a minimum gas fee route in the decentralized exchange to help me place an order. Here is a recommendation for me to use JupyterSwap. Then I want to turn this 5000U into Thales. Here you can see the gas fee, the point of sale of the transaction, and the interest rate of the swap.

After the trading is done, I will enter my PIN code and it will start to order. After the trading is done, you can see here that I used 5000U on January 1st this year and exchanged 631,982 Thales through JupyterSwap.

The fee is 0.3% and I used 5U gas fee If I have Solana in my wallet, I can save a little gas fee Because I don't have it, there is only USDT in my wallet So Biget Wallet also automatically changed the U to gas fee to do the transaction through DEX You can also do some cross-chain swaps on it Because they support more than 100 main networks, it is also the most supported main network Web3 wallet

As for the complexity of the use, it is medium-level. I personally think that the interface of Big Ed Wallet is very simple. And they also support various different languages. Another biggest advantage is that you don't need KYC. Anyone in the world, anywhere, as long as there is a network, you can use it. If you may not feel it in Taiwan, but in the United States, there are actually many international exchanges that Americans cannot use.

There are very few exchanges that Americans can legally use, such as Coinbase and Crypto.com. There are very few options for B-type exchanges using these US-based exchanges. Because the US is very strict about financial supervision. But today, through Web3 wallet, you can do any transaction you want on the blockchain completely freely. And it's completely anonymous. No one knows what assets you have or what you bought. Because Web3 wallet doesn't need KYC.

Let's take a look at some of the main differences between Web3 wallets I found some more famous ones like Metamask Trust Wallet is a must-buy Web3 wallet BigGap Wallet is the one I just used Its predecessor is BigKip and was acquired by BigGap The other is OKX Wallet, which is a Web3 wallet developed by OKX Speaking of Metamask, I think the reason why you think the small fox wallet is difficult to use is mainly because the support network is too small

They are still only supporting EVM. Trust Wallet has more than 70 support groups. BigEd Wallet has more than 100 support groups. OKEx Wallet has more than 70 support groups. The more support groups, the more B-Card you will support. If you use Little Fox, you can only use ERC20 tokens.

If you are playing coin, Biget Wallet and OKX Wallet have a good interface. You can see a lot of hot list on the top and some low app lists. I think this is also an advantage of these Web3 wallets. If you have used Metamask, you should know that its interface is very good.

In addition, they also have a K-line map to see BigGap Wallet also has some magical features like smart money tracking, you can play with it yourself Bitcoin transactions can only be done on Trust Wallet and BigGap Wallet, and others do not support Bitcoin network

Oh, Big Ed Waller has an "invite friends" function. If you use it later, you can also enter my invitation code in the invitation center of your wallet. I will put my link and invitation code in the information bar at the bottom of the video. All Web3 wallets support DeFi-supported currency. In addition to Metamask and Little Fox, other Web3 wallets also support DeFi currency. Of course, in the Web3 wallet, in addition to currency storage, you can also store your NFT.

After Big Ed Wallet, they will also launch a bank card. Currently, there is no open application yet. If there is an open application later, I can make a video to share with you. I think these bank cards are mainly to build a bridge from Web3 to Web2 traditional financial systems I saw a lot of netizens leave comments saying that these cards have high fees or exchange rate is not cost-effective. Yes, maybe these cards are not yet Web2 bank cards to be mature. Because Web3 has just started

So if it is connected to Web2, the fee will be higher. And we are all quite lucky. Because the countries we live in have a perfect banking system. Basically, as long as you don't have a bankruptcy or your credit is OK, you can get a bank card. But not every country's people can easily do this. So I think these Web3 companies are trying to build a bridge with Web2. In fact, it has contributed to the overall web3. So I don't think it's bad. If you don't think this card is for you, don't do it.

Now let's show you how to use Web3 wallet. You can download BigEd Wallet from App Store. Open the app and create a new wallet. You need to set a password. This is your transaction password. It's like your phone's PIN. After setting up, your wallet is created. Before you do anything, I suggest you prepare the address first.

You can click here to go back Then the back pack of your cold wallet is exactly the same as the back pack Remember not to put these notes in your password management program or photos and so on Because this is the only thing that can restore your privacy Even if you accidentally forget your password today

You can still use this set of hostpages to restore all your private keys. When you restore, you can re-establish a new wallet. Then your password can also be reset. If you lost your hostpages today, and then you deleted your app or your phone, it's useless to find BigEd. Because they won't put your hostpages and private keys in any place.

Only your phone app can see your address. After the address is prepared, you can go to the wallet and choose the network you want to choose. There are more than 100 types here. For example, we choose Slana and then choose USDT.

Now I want to transfer my USDT to my Web3 wallet I click on "Sell" OK, it will display my wallet address here At the same time, I can open my exchange app Oh, remember here When you transfer your U, you must choose the correct network If you transfer your U to an address that is not the same network, then your U may disappear No one can help you get it back

Alright, that's all about Web3 wallet I think it's pretty good and completely free You can play it yourself Why do I use Biget Wallet? In addition to their good work They have a $300 million insurance fund If today is the problem of Biget Wallet itself Causing your asset loss You can ask them for compensation

They will use the $300 million of prepaid funds to repay As far as I know, other Web3 wallets do not provide this extra insurance In addition, the gas fee of BigGet Wallet can also be paid with BGB BGB is the platform currency of BigGet The two ecological chains are common The reason why BGB has become very fierce recently is because BigGet Wallet has started to be used by many people Of course, I don't own any BGB But through BGB, users can save a lot of money in the exchange and Web3 wallets

BigGad Web3 wallet and exchange can also be linked to bind to get some exclusive benefits for wallet users. It is also convenient for you to participate in some currency activities and asset conversion. Okay, that's it for today's video. Thank you very much to BigGad Wallet for sponsoring this video today. Of course, before using any wallet, I would recommend that you do your homework first to understand the risks. Of course, this video is not an investment suggestion, nor an opening suggestion, nor a suggestion to use a wallet. I just share this information. See you next time.
