Can Ethereum investment be refunded

1. In fact, the rise and fall of digital currency is a normal situation. The key is to see whether you are optimistic about its long-term value. Relatively speaking, if the long-term value is worth investing in, then the short-term decline can be ignored. At the same time, if you don't know much about digital currency users, it is recommended to choose a reliable and good platform for investment. The investment period needs more than six years, Word of mouth should always be good, you can take a look at AEX, fire coin these two, but also more reliable, you can also understand their own network first
2. If you can't withdraw cash, it's the platform you're playing. Just find a professional to help you get it back
3. Note that Ethereum is 2.0 now. As of 13:57 on the 4th, the current deposit contract address of Ethereum 2.0 has received 1000098eth, and 31252 addresses have completed the mortgage of 32eth. With the increasing number of mortgage, the annual yield of mortgage will graally decrease. After the mortgage amount reaches 1 million eth, the current annualized yield is about 15.7%. Zhongyuan, a well-known exchange, has taken the lead in opening the mining channel of eth2.0 verification node, and then launched qeth. Users can invest their own eth in verification node mining and exchange qeth to obtain liquidity, and then participate in mining. Compared with the disadvantages of eth2.0, qeth has too many things: the liquidity is guaranteed, the user does not have to bear the technical cost, the threshold of participation does not need 32 eth as low as 0.1eth, the nodes are maintained by the platform, and the income is distributed according to eth2.0.
4. Although the domestic exchanges were completely shut down in 2007, overseas exchanges are still open to domestic investors, such as the domain kingdom. Ethereum is the world's second largest virtual currency by market value, second only to bitcoin. Although the price of Ethereum has been falling in recent days, it can still be invested because it can also buy profits when the market falls.
5. Of course, it's worth investing. Ethereum has broken a new high for the second time. It's up to $1414, but we don't recommend catching up. Can go to the currency to play spot, currency spot trading, safe and stable, not burst. Suitable for ordinary investors.
6.
Ethereum from 1.5 yuan to 270.5 yuan, the trend is unexpected
7. As a bitcoin trading platform, fire coin has won a round of 10 million RMB capital investment from Zhenge fund, Dai Zhikang, Sequoia Capital (shareholders of many global well-known companies such as apple and Alibaba). Fire coin implements strict risk control management and operates stably. As of the end of 2016, the accumulated turnover of fire currency reached 200 billion yuan
on September 15, 2017, huoyuan.com announced that registration and RMB recharge services will be suspended from now on, and all users will be informed before September 30 that they will stop trading. At the same time, all transactions of digital assets against RMB will be graally stopped before October 31. Fire money network said it will stop virtual currency trading on October 31, 2017.

8. The issue of bitcoin is determined by the block height, that is, the distance from the No. 0 block of Genesis. Now when the number is reached, the total amount of bitcoin should be limited. After this village, there will be no store. If the miners dig a block but don't receive the reward of the block, the bitcoin will be destroyed forever
coinbase transaction is a special transaction that generates bitcoin "out of thin air". Only miners can write this kind of transaction, and the number of generated bitcoin is limited by rules (new currency reced by half for every 210000 blocks + transaction fee for this block)
however, the rules do not stipulate that the miner must take away all the rewards that can be taken, and can choose not to take them
therefore, a mine pool connected with the RSK side chain has made a bug before, forgetting to take away the reward and occupying a pit in a block for nothing, which is equivalent to destroying the corresponding amount of bitcoin, making the total amount of bitcoin decrease a little bit permanently
in addition, to spend a bitcoin, you only need to specify the transaction ID and output serial number
as like as two peas in multiple blocks repeatedly write identical coinbase transactions, the transaction ID is also repeated.
therefore, this kind of situation also occupies the pit of a block in vain, and permanently destroys the corresponding amount of bitcoin
it seems to me that this is still a security vulnerability, so the new version of bitcoin software later banned the writing of repeated coinbase transactions. But until now, there has been no ban on miners not getting their e rewards
generally speaking, a coin is controlled by a private key. If a coin is transferred to an address where no one knows the private key, it will be destroyed
if the owner does a good job in security, and the private key is not disclosed and cannot be guessed, but he accidentally loses the private key, it is equivalent to destroying all the coins he owns
there are only some special circumstances that require intentional destruction of coins
one is irreversibly converted into another kind of currency, such as the contract currency XCP attached to bitcoin and wormhole cash WHC attached to BCH
the second is to save certificates and data on the chain, such as the time stamp: panbiao.com/2013/08 /
and the crowd funding of the original Ethereum founding team: zhuanlan.hu.com/p/29
the private key is essentially a big number. Whoever knows this number can control the currency on the corresponding address. So the private key must be generated with reliable random number, otherwise it may be guessed and stolen
compared with the token, the address is the hash of the public key. There is no way to judge whether an address has a corresponding public key and private key (even if the public key is known, the corresponding private key cannot be known). Therefore, even if it is explicitly the address of "burned" token, the system does not prohibit the transfer in
strictly speaking, what locks the currency is a small program (script). This program takes the input as the public key and digital signature. First, check whether the public key hash is consistent, and then check whether the digital signature is valid. If it is valid, it will be verified and transfer is allowed; Otherwise, it will be judged that the transaction is illegal and refuse to package into the chain
it is the whole node software that explains and executes this program. It can be said that the software code of the whole node specifically defines a coin
however, the current situation is very embarrassing. Most miners do not run the whole node, only a few mines are running. The vast majority of users do not run the whole node, even if they run the whole node, they can only perform verification, no computing power, no block
