1.
The price of Eth and other virtual currencies is determined by the following aspects: 1. Frequency of use; 2. Actual use; 3. Number of participants
as for how much room to go up, the current price of Ethereum is about 6600. Recently, e to the frequent use of Ethereum private placement, Ethereum has risen to more than 10000. Ethereum is a smart contract, and there are countless tokens developed based on Ethereum. Therefore, as the underlying public chain of smart contract, its prospect changes with the popularity of blockchain, However, some time ago, the disadvantages of Ethereum were exposed. The main chain was congested and the handling fees were extremely expensive. The development of Ethereum was close to the bottleneck. Therefore, the room for its growth was whether the developers could improve the main chain environment according to the disadvantages. As for the number of participants, it was not a big problem now. Pay more attention to the current development progress of the developers and focus on doing things, There is a bright future ahead
at present, the websites that can trade Ethereum include: btctrade international station, Huo coin, coin an, etc.

6. How to match adventure and mining team with hero mining team
recommendation on matching adventure and mining team:
five tigers may be a big fool in other games, but Huang Zhong and Zhao Yun may be the only heroes who can play a small role in adventure and mining. Why do you say that? Because these two heroes also need to be changed in the later period
first of all, let's talk about the two heroes Guan Yu and Zhang Fei. This time, Guan Zhang is the most useless. The attributes of these two heroes are not necessary, and the extreme attack is also very weak. As for fitness skills, heroes don't want them. What's the use of fitness skills
five heroes provide 12 defenses, which is a very poor conversion. It's not as good as the last two tristans, which directly have 11 defenses. Or it's easier to use five defense heroes directly
the following points should be noted:
1. When you are ready to make a breakthrough with 72m, you'd better keep the experience value above 7m. After breaking through the first two levels, the cost performance is particularly high, especially the first level of 5-sense 10 - & gt; 11. It only needs 2.14M experience, but it can increase the combat power by about 5K. The second level will require more than 5m experience, and then more than 7m, so the cost performance will become average
2. After four sleeps, the character should get to level 20 on average, because the price performance ratio of the first 20 levels of four sleeps is also very high. The 20-30 price performance ratio is extremely low. However, we can't do it in this period. There's no way. We can plan it ourselves.

7. Ethereum, or eth for short, is a hot virtual investment currency recently. Known as the world's second largest market value of digital currency, second only to bitcoin
Ethernet coin is a kind of digital token of Ethereum, because Ethereum needs to use the token eth to support the application. Ethereum can also trade on trading platforms. In short, Ethereum is a platform and a programming language, which enables developers to build and release the next generation of distributed applications
Ethereum can be used to program, guarantee and trade, as well as to organize voting, domain name trading, financial trading platform, online crowdfunding, management company,
formulate contracts and most of the agreements, and integrate intelligent assets of hardware
the reason why the price of Ethereum can soar is not only e to the promotion and publicity of Ethereum community, but more importantly, virtual currency investors are looking for investment procts to replace bitcoin
a series of problems, such as bitcoin being regulated by the domestic central bank and being refused to apply for ETF listing, have led investors to look down on the prospect of bitcoin. At this time, the emergence and promotion of Ethereum are favored by these virtual currency investors
btctrade platform (bitcoin trading network) www.btctrade.com As the largest and most reliable trading platform in China, Ethereum trading was launched as early as November. Ethereum was about 50 yuan when it was online, and now it has risen to 300 yuan, which is amazing! It remains to be seen whether the future of eth will be as good as bitcoin!

8. Ethtrade Ethereum trade is to move bricks with virtual currency to other platforms and sell them at 685 or 690 or even higher prices. This is horizontal arbitrage! Another is vertical arbitrage.
9. First of all, what is Ethereum? Ethereum is a programming language as well as a platform. The Ethereum that investors / speculators pay attention to is actually Ethereum, which is a digital token derived from Ethereum - eth Ethereum.
whether Ethereum has investment prospects, we only need to see its value, which increases from tens of yuan to hundreds of yuan, Not to mention the future bubble or not, the space for appreciation at this stage is worth our attention.
Ethereum trading platform, at present, I recommend btctrade platform (bitcoin trading network), which is a relatively reliable trading platform in China! Ethereum was launched in 2016, and the rise of currency price is amazing!
