The latest introduction of POS in digital money market
about digital currency, let's talk about it. If you think it's unreasonable, you'll laugh it off
money, as a measure of transaction value, does not necessarily have value in itself, it can only be used as an intermediate unit of measurement. It's just like China has only RMB as legal tender, that is to say, government guarantee has value. For example, in those war-torn areas, ten jin currency may not buy an egg, which is the reason
back to digital currency, digital currency, until now, no country has recognized it as the currency in circulation of its own country. It seems that last year or the year before last, our country also banned some. In this case, digital currency can only be sold at a price higher than your purchase price, so that you can make money. But digital currency itself does not have any value. Unlike stocks, it is your ownership of listed companies. So if you can't find someone to buy digital currency, it's worthless
the Ponzi scheme in history, the Dutch tulip, when it was the most expensive, a tulip was worth buying a house. When no one bought it, all the tulips rotted. In addition, they couldn't get a potato. Therefore, Buffett said that digital money is a bubble, which is a hoax.
in addition, there is a saying in the stock market that when all the ladies in the vegetable market begin to discuss the stock market, it is the time when the stock market reaches its peak. In my opinion, this also applies to digital currency. When many people are discussing how to make money and how to make a lot of money, the risk has accumulated to a great extent. Most of the time, when the stock begins to fall, many people are still in the previous inertial thinking, thinking that it will rebound soon, and then it will get lower and lower, and they are more reluctant to sell it. This is why many people hold a high position on it
I'm not sure if it's the highest point of digital currency, but I think that digital currency, which can be issued by anyone, has no value as currency circulation and can only be sold to others. I think it's a fraud.
as time goes by, half of a year has passed. Now let's review the market trend of bitcoin in 2019. After last year's bear market, the trend of bitcoin has been at a low ebb, with the lowest falling to 3155. After that, on the first day of the new year, it will enter a state of shock and energy accumulation, It wasn't until about 8 a.m. on April 1 that the market ushered in the dawn. During the rise at 4000, the market experienced a period from 9000 high in May to 13970 high in June. During this period, many friends who were trapped in high positions last year were out of the game or entered low positions to gain profits. After the market in June, the overall trend of bitcoin entered a callback state, After digesting the sequelae (large volume) brought by the rising trend ring this period, the fluctuation range is between 9000-10000. The wave was used for nearly two months, and it started a new round of pull-up at the end of July 21. After reaching 12500, it is now in a state of callback. How do you view the overall direction of the later disk
although the market in the past two days is in a state of correction and repair, the overall market trend of bulls is not finished, but hidden. From the weekly market, we can see that the bull's rising space has not yet come out completely, but is waiting for a new round of rising at the bottom of the market, and the weekly bullion belt index is all up, In this week's market, we can see that the rally and the callback account for half of each other, and the long rally is pushed by the energy and there is a sharp decline. This is a signal. The key to the sustainability of the long market is the update of the market index next week. If the momentum of the long market does not enter the market, the market will change, Please take a rational view of the trend
at present, the daily short position is graally strong in the evening, and the daily indexes of Ma5 and ma10 above the market show signs of dead cross downward. As long as the daily line of ma10 is shifted downward, there will be a short-term decline. Although 11400-11200 below is the short-term support of the daily line, as long as the short position of Ma5 and ma10 above the market touches the hundreds of points below, it is impossible to hold, At that time, 11000 is the watershed, so we need to pay attention to the short-term pressure range of 11800-11700. The 4-hour market is in the stage of rebound from the recent decline reaching the bottom of 11400. At present, the pressure above the short-term market is 11700. If the rebound kinetic energy does not reach the top and the lower Ma5 moving average continues to decline, then the short market will continue. This is the point that should be paid attention to by friends who are staring at the market at night
the operation idea is that if the market rebounds to the upper 11700-11800 pressure range, then the target range of 11500-11400 can be seen under the entry empty order, and 11000-11200 can be regarded as the bottom in the short term if it can continue to be short, and the bull short-term change needs to pay attention to the upper 11700 pressure position, and if the market rise breaks and stands firm, then the entry empty order can test the upper 11800-11900, The overall idea is to take short positions as the main method and take long positions as the auxiliary method.
if you have a friend who has an operation, take stop loss and stop profit, and do a good job in risk control. If you don't understand the market analysis or understand it in the early stage, please enter the market cautiously. I hope you can plan the worst result for every operation. After all, it's all real gold and silver, and your own hard money, It's best to be able to afford the return of your own efforts. Of course, some friends need to keep in touch with shanghua operation, and they will pass it one by one later
2. The circulation of next year will decrease 10 times. In theory, X2
3. The current price of eth is 230x4 = 920 US dollars (upgrade + expected price after proction rection)
ring this period, the return comparison between holding spot and ETF fund is as follows:
1. Holding spot makes 4 times of profit
2. Holding Ethereum ETF fund launched by bitoffer, the income starts 12 times, Up to 30 times (intelligent position adjustment + fund compound interest calculation)
there is no doubt that Ethereum ETF is the best investment choice!
Private key: in fact, it is a group of random numbers. We have already introced the random numbers in the blockchain
public key: the private key is generated by elliptic curve encryption algorithm, but the private key cannot be obtained by public key inversion. The function of public key is to encrypt information with one's own private key when dealing with the other party, and then the other party decrypts the original information with one's own public key. This process is commonly known as signature
address: because the public key is too long and inconvenient to use in the transaction, the public key hash is encrypted with sha256, ripemd160 and base58 algorithms to generate the address
first, the random number generator is used to generate a "private key". The subsequent public key and address will be generated by the private key, so the importance of the private key can be summarized in one sentence: & quot; Who has the private key, who has the right to use the wallet& quot;
"private key" is encrypted by elliptic curve algorithm (secp256k1) to generate & #; Public key;. This is an asymmetric one-way encryption algorithm. Knowing the private key can calculate the public key, but knowing the public key can't reverse calculate the private key
"public key" generates "public key hash"
through one-way hash algorithm (sha256, ripemd160), and connects a byte of address version number to the "public key hash" header (for the pubkey address of bitcoin network, The first four bytes of the result are used as the check value of "public key hash" and connected at the end of it
encode the previous result with base58 (customized version of bitcoin) to get the "wallet address"
