Shortcomings of bitcoin

1.

(1) bitcoin was originally a kind of network virtual currency to buy real-life goods

(2) advantages:

< UL >

completely decentralized, without issuing institutions, it is impossible to manipulate the number of issues

anonymity, tax exemption and supervision free

robustness. Bitcoin is completely dependent on P2P network and has no distribution center, so it cannot be shut down externally

cross border

it's difficult for the cat to survive

< / UL >

(3) disadvantages:

< UL >

the vulnerability of trading platform

transaction confirmation takes a long time

the price fluctuates greatly

the public did not understand the principle, and the traditional financial practitioners resisted

2. Bitcoin is a virtual cryptocurrency based on decentralization, peer-to-peer network, consensus initiative, open source, and blockchain as the underlying technology. It was proposed by Nakamoto in 2008 and born in 2009
bitcoin does not have a centralized issuer. It is generated by the calculation of network nodes. It can be bought and sold on any computer connected to the Internet, and has a strong scarcity
Decentralization: bitcoin is the first distributed virtual currency. The whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom

Global Circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

exclusive ownership: private key is required to manipulate bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself

low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution

no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome quota and proceres. If you know the other party's bitcoin address, you can pay

cross platform Mining: users can explore the computing power of different hardware on many platforms

3. There are several problems in the development process of bitcoin:
1. Supervision. Decentralization is the biggest advantage and the biggest disadvantage of bitcoin; Because it is easy to be used for illegal trade
2. The problem of trading platform. At present, the domestic bitcoin trading is closed, but the foreign bitcoin trading market is hot and there are many platforms, so it is difficult for users to distinguish the legitimacy of the trading platform
3. As for the transaction risk, the bitcoin development team is only responsible for the development, maintenance and improvement of the bitcoin system, but it is unable to guarantee the normal progress of the transaction
4. As for the identity of the trader, generally speaking, the trading platform authenticates the user's real name, but the coin pack thinks that there are still some loopholes in this kind of authentication
5. Legitimacy. Because different countries have different views on bitcoin, they have different views on bitcoin.

There is a very good answer, the invasion and deletion

cryptoclones is a digital and collectable blockchain game based on Ethereum blockchain. Using ether money to adopt clowns can be resold, and they can also be used to breed a new generation of clowns with strange shapes. They can also be cultivated to work and earn money, which makes the digital collection of clowns more sustainable and playable< There are two kinds of proction mechanism of clowns, one is official proction, the other is breeding proction between two clowns
one official clown is proced every 15 minutes, and the total number is only 50000. At certain times, the official will also release some strange clowns with special shapes. The price of the original clown is the average of the prices of the last five clowns in the market
two clowns of different genders can reproce in the breeding center of the market. In each breeding pair, one clown who plays the role of father can receive the breeding fee paid by the other party (maternal Master). After breeding, there is a certain recovery period, which is related to the clown's genes. The clown in the role of mother will have a period of pregnancy, and she will not be able to breed with other clowns until she gives birth to her baby. There is no limit to the number of breeding times of each etheric clown, but the recovery period and pregnancy period will increase with the number of breeding times< Each clown's appearance is determined by the tamperable genes stored in the smart contract, and each gene is unique, so each clown is unique
the appearance of a clown is composed of eight parts, each part of which can be divided into ordinary and rare attributes. The number of rare attributes is less than that of ordinary attributes, which makes the clown with rare attributes more precious
the appearance of a clown born in breeding is closely related to his parents and the genetic genes carried by his parents. The offspring have a high probability of inheriting the shape of some parts of his parents, so that their parents' good genes can be inherited, and it is possible to mutate and become a completely different clown from his parents

3. Clown trading

etheric clown can be directly used for trading
sell: users can choose clowns to be auctioned in the market, and they can sell their own clowns. When selling, users need to set the highest starting price, the lowest acceptance price and the auction time. The Dutch auction is adopted in the auction. During the auction time, the highest price set by the seller is graally transferred to the lowest price. If the owner is not willing to sell at a low price, a longer auction time can be set or the clown can be sold off the shelves
buy: the buyer selects the clown on sale in the market and pays ether to buy the clown he likes. When the buyer purchases, the transaction will be concluded at the auction price at the current time point. If you have a favorite clown, but feel that the price is not suitable for the time being, and want to pay more attention, you can collect the clown after you like it. Later, we can understand the dynamic of the clown through "my attention"< There are four kinds of clown attribute values: growth value, strength value, agility value and wisdom value. Generation 0 clowns get the value of each attribute randomly, and the non generation 0 clowns are mainly inherited
attribute values can be changed by eating food
after the clown's growth value reaches the requirement (100 points), he can go to the factory to earn money (ETH). Different kinds of factories need different clowns. Dream college needs the wisdom of every working clown. Clowns with more than 800 points of wisdom go to Dream Academy of Sciences to work, and their income can get bonus. If a clown with less than 300 wisdom goes to work, his income will be reced to
a part-time job will consume physical strength. The total physical strength is 120 points. It consumes 1 point every 12 minutes and can work up to 24 hours. During the period of not working, physical strength can be recovered, a little every 8 minutes
when the time reaches 0 o'clock or the clown's physical exertion is completed, the clown's work income will be settled according to the actual working hours at 0 o'clock every day. When every 12 minutes is a work, less than 12 minutes will not be counted

5. Clown food and feeding

owners can buy spinach, beef, carrots, walnuts and other food through the mall to feed clown pets
the price of food is related to the selling price of original clowns on the platform the day before. So the owners can hoard some food when the price of food is low
feeding spinach is helpful to growth value, beef corresponds to clown pet's strength value, carrot corresponds to agility, walnut corresponds to wisdom
the clown can only eat one food a day. We suggest that spinach should be fed in the early stage to meet the working conditions as soon as possible, and then according to the natural properties of clown in the later stage. When working, choose the type of factory with the highest attributes to work

The price and quantity of purchase can be set in the price limit. Only the amount of RMB purchased can be entered in the market price column. The minimum bitcoin purchase of fire coin is 0.00000 1

according to the market price (71193.96usdt / BTC), it is 0.01018511 usdt. Once the balance of your usdt account is less than this number, it shows that the available quantity is insufficient

extended data

this is displayed in the usdt trading area, which means that you don't have enough usdt to buy bitcoin. BTC / usdt means buying BTC with usdt, so your usdt stock depends on how much BTC you can buy< br />
