2. BTC is bitcoin, bitcoin, abbreviated as BTC, is an electronic currency proced by open-source P2P software. It is a network virtual currency with high security, high encryption and decentralization. It is not supervised by a single department or indivial, but by all the people who hold bitcoin
bitcoin features: no freezing, no tracking, no tax, and extremely low transaction cost. Compared with people who speculate in currency, it is wealth, and people outside the currency circle may think it is a fraud
at present, the mainstream digital currencies include bitcoin, Ethereum, bitcash, EOS, Ruibo, etc., which can be properly invested, and the transactions are risky, so we should invest cautiously.

From the current technology, the next bitcoin in the bitcoin data structure can be divided into 8 decimal places, so the minimum unit of bitcoin is 0.00000001btc, but the transaction can not be so small

according to the statistics of bitbao, at present, the common minimum trading unit of bitcoin trading platform in China is 0.01btc, so the 0.0001 proposed by the owner is not available for sale< br />

4. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. 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< On February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that relevant institutions would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees
hope to adopt

the hoe is on the left side of the light in brown crystal mine entrance
then dig gold ore in brown gold mine cave
finally enter brown crystal mine through the game of Crystal Palace in brown mine entrance. Dig crystal ore on the crystal stone in the lower right corner. The big black stone in the lower right corner of brown mine entrance can be g three times a day, Then go to the Labrang gold mine, and the gold on the right side of the door can also be g three times a day. Then go to the purple stone in the lower right corner of the Labrang crystal mine, and you can also dig three times a day. Hope to adopt

6. This is a composite statically determinate beam, which can be disassembled into two parts. The reaction force acts on the two structures, which is the interaction force. First, study the left structure. According to the balance, it can be concluded that the reaction force is f / 2, then the right structure is also subject to the same force, and the hinge C will have a downward displacement. According to the deformation compatibility, the hinge C on the left will also be downward. The displacement of point a of the left structure is 0 under the ideal constraint, which means WC / 2. In addition, the left structure is also subject to the action of F, so there is no problem with the answer.
