Can bitcoin be counterfeited

1.

Unfortunately, bitcoin is no longer tradable in mainland China. Bitcoin China announced that it will stop all trading business on September 30, 2017

development information:

after bitcoin China and microbit, the bitcoin trading platforms in Shanghai and Shenzhen, respectively announced that they would close their trading business on September 30, 2017, on the evening of September 15, two other large domestic bitcoin trading platforms, Huo coin.com and okcoin.com, headquartered in Beijing, announced that they would suspend their registration from 21:30 on September 15, 2017 RMB recharge business; All users will be informed before September 30 that they are about to stop trading, and the trading business of all digital assets against RMB will be graally stopped before October 31

according to worldcoindex data, since September 1, bitcoin has dropped from $4800 to $3655, a drop of 24%, and its market value has shrunk by nearly $20 billion

in the same period, the decline of ether currency and Wright currency was 37.5% and 31% respectively. Over the past two weeks, Leyte currency has declined by more than 40% on the three major domestic trading platforms

According to analysts at Goldman Sachs, bitcoin can become a legal and widespread form of currency, but it is mainly possible in theory

Analysts believe that the reality is that cryptocurrency still has a very high threshold in most places. First, the government cannot track who is buying or selling bitcoin. And as we all know, the price of cryptocurrency is very vulnerable to large fluctuations. This volatility is very rare in legal tender, so bitcoin is not suitable to be a reserve currency

3. First of all, let's talk about the background. The basic principle of bitcoin "account" is key public key address. You can roughly understand it as "key box box number". Now is to start from the box number or box to crack the key
there are basically two kinds of attacks, one is dictionary attack, the other is brute force attack
dictionary attack is to use common passwords and their simple variants as keys one by one. As long as your pass phrase is not hard enough, the possibility of successful attack is very high. So if you want to use this, you need to popularize the knowledge of cryptography first, and don't think it's very safe to add a long password
if you don't use the wallet generated by pass phrase, you can only crack it violently, which is equivalent to enumerating all the possible keys. At present, this is impossible, even if the electronic computer is becoming more and more powerful. However, quantum computer can do it theoretically, but don't worry too much. If such a powerful quantum computer comes out, it will not only endanger bitcoin
at the same time, bitcoin has a second layer of protection: if an address only accepts bitcoin but does not output it, its public key is confidential, that is to say, no one else can see the box, only the box number. At present, the process of decing the box from the box number can't even be done by quantum computer. In other words, if there is a quantum computer, bitcoin has a last line of Defense: it's temporarily safe to transfer your money to a new address
finally, some time ago, the wallet generated by the Android client was attacked because of a bug in the underlying random number generator. In fact, this function is not random securerandom, which Google quickly admitted and fixed. It's hard to say whether this kind of thing will happen again, but I don't think we need to worry too much.

4. Osmanthus fragrans is a variety with strong suitability. As long as the pruning is moderate, the water and fertilizer management is in place, and the light conditions are good, the flowering period of the year can be seen; Full flower depends on the planting conditions and management level, generally has two years of recovery period is almost
however, Osmanthus fragrans should not be planted on the roadside with poor st conditions, because the st will affect the photosynthesis of leaves and lead to non flowering
when transplanting Osmanthus fragrans, the mud head should not be scattered, and the seedlings should be planted within one day. After planting, the seedlings should be drenched in time, at least twice a day. Water should be inserted for the first time, that is, the roots should be filled with mud, pruned properly, new buds can be grown to prove survival, and fertilizer can be applied after one month, so that they can blossom in the same year

5. This kind of virtual currency depends on its specific function
for example, if it's Q currency, it's definitely worth investing
except for this kind of virtual currency which is widely used and almost everyone knows it, no other currency is worth investing
except for the point card Yuanbao of a large game
but Q currency or the point card Yuanbao of a large online game They won't let you invest in it.....

6. Bitcoin is a virtual currency
investment risk is great
it is basically a black market transaction
not advocated by the state
at the same time, there is no way to ban it.

7. BSC BTS
is called ABIS port
BTS and MS
is called um port, that is, air interface
there are actually two interfaces between BSC and MSC, because there is also a TC mole, and the two interfaces are ater port and a port respectively.

8. The old BSC is converted into optical signal through 2m line to SDH multiplexing equipment, and then the optical transmission network to the transmission equipment on the base station side is converted into 2m line to form electrical signal to the base station (BTS)

the new BSC is basically optical port BSC. Go directly to SDH or PTN equipment on the transmission side, go to the base station side through the transmission network, and convert it into 2m electrical signal to the base station (BTS). Some base station equipment support the optical port, and may be directly inserted into the optical fiber.

bitcoin is a virtual currency and has no issuing institution

Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million

bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items

10. Picture can p voice can be changed, video editable, banknotes can be printed, then the electronic form of Alipay money can be faked? Is bitcoin mining fair and aboveboard? If you want to have a good meal, I want to go to bed and remember that I will come back to work this morning. What you can do is that he is far away from the car in front of the broken mobile phone screen at this point? This kind of person is like this, because he in this love story, including him, dare not face you, the heart is strong, do not want to go to the concert, so I will be more sad!
