Digital currency in exchange or purse

1. Fire money is the circulation market for buying and selling money, and Shang money is the wallet for saving and earning money, similar to the concept of yu'e Bao

2.

The digital currency wallet is the hardware wallet, which means that the private key of digital assets is stored in a single chip, isolated from the Internet, plug and play. Hardware wallet can't guarantee 100% security. For example, if a geek gets your hardware wallet and doesn't know your private key, it may be cracked by violence. It's just one of the safest storage methods compared to other storage methods

many block chain entrepreneurs at home and abroad are optimistic about the development of this field, so they begin to build more hardware wallets. In the case of the exchange being stolen a lot of money and the software wallet being stolen from time to time, many investors regard the hardware wallet as the last moat

extended information:

whether the hardware wallet is safe

the hardware wallet can not guarantee 100% security. For example, if a geek obtains your hardware wallet, it may be cracked violently even if it doesn't know your hardware wallet immediately. It's just one of the safest storage methods compared to other storage methods

of course, there are exceptions, such as you have unlimited brain power and never forget. It's better to save it anywhere than in your own mind

3. The answer is yes
when transferring money, the receiver only needs to send the address of the wallet to the other party, and the other party can transfer the digital currency to the address. When trading in the exchange, the user should also enter the digital currency into the address designated by the exchange, that is, the wallet, to complete the transaction. At the time of withdrawal, the exchange will also enter the digital currency into the user's wallet address accordingly. This is how the money should be transferred to the wallet.

4. In 2013, vircurex, the third largest trading platform of bitcoin in the world, was attacked twice by hackers, which made vircurex fall into a serious financial crisis. As a last resort, it stopped withdrawing bitcoin, Leyte and other virtual currencies in March 2014
on the morning of February 25, 2014, Mt. GOx, the world's first exchange, stolen 744408 bitcoins in a major bitcoin theft case. According to the average price of bitcoin on the 28th day, it is equivalent to 475 million US dollars. Mt. GOx went bankrupt
on January 26, 2018, coincheck illegally removed about 260000 NEM holders at about 02:57 on that day, and then suspended some functions
on March 7, 2018, the world's second largest exchange, "coin on binance exchange". A large number of users' accounts were stolen. In the face of the hacker attack, this morning, coin an rolled back all abnormal transactions
the above lesson of xuelinlin tells us that no matter how big the exchange is, it can't guarantee the security of core assets and users' digital currency

8. I think it's convenient and safe to use kushenleng wallet, because the part storing digital currency can only communicate through two-dimensional code, it won't touch the network, and it's very safe to store.

9. If you want to invest in mainstream digital currencies, you can buy them in some well-known digital currencies, such as coin an, okex and Huo coin. These exchanges all have strict censorship mechanisms. Generally, they are mainstream digital currencies such as BTC / eth / EOS. If you want to keep it for a long time, buy it and transfer it to your cold wallet. Don't put it in the wallet of the trading platform
if you want to invest in some non mainstream digital currencies, you can choose BZ, ZB, OCX, bcex, etc. relatively speaking, these digital currency exchanges will have more currency choices, but the opportunities of meeting air currency will also increase.
