T1: eth (the first public chain at present, the underlying platform of Shanzhai coin breeding, and in the speculation of eth2.0) EOS (community consensus + DAPP possible explosion + defi can also join + drop out of high cost performance) Zec (anonymous leader)

T2: Yas (UBI concept, low market value, great potential) atom (cosmos, advantage new public chain), XRP (the decline in 2019 has not risen, so the upward space is still very large) Polkadot dot (Boca, the goal is to surpass Ethereum) KSM (Boca pioneer)

T3: Ada (potential) NEO (myth of 1000 times of the last bull market), ont (strong village), Iost (Iost is currently undervalued, DAPP is also in good development)

4. 1. Bitcoin
it is the birthplace of blockchain technology, and the market has confidence in it. It still maintains a stable growth under the adverse situation of major policies. Once it solves the problem of capacity expansion, the price rise can be predicted
2. Ethereum
compared with bitcoin, the advantage of Ethereum is that it has no policy problems. Although the event led to its bifurcation, the establishment of enterprise version Ethereum alliance may solve this problem. Its concept and Prospect of smart contract attract many developers to follow
the essence of community operation is that the majority decides the minority when indivials support eth
3. Zec
compared with bitcoin and Ethereum, the risk of z-coin will be greater, and its value will take a longer time to reflect. But in the long run, the value of anonymity will be one of the values that human beings generally pursue
4. BTS
bitstocks are very powerful and the system is very stable. Decentralized trading, anchoring system and so on. Although the founder bm's brain damage has hurt the community, the value of bitstocks is obviously undervalued. It is a wise choice to hold bitstocks on the cheap.

Digital currency transactions trigger public opinion, decentralization? Blockchain? What is bitcoin

since 2016, when the market value of bitcoin (or rather the exchange rate) began to soar, this not new word has entered our lives. Why does bitcoin have such amazing value? One bitcoin equals $20000! What mystery does it contain? Today, let's talk about bitcoin

it has always been a mystery who Nakamoto is

6. According to the crushing mode and mechanical structure characteristics (action principle), the crushers can be divided into six categories:

(1) jaw crusher (tiger mouth): the crushing action is to periodically press the movable jaw plate to the fixed jaw plate to crush the ore block in it

(2)
cone crusher: the ore block is between the inner and outer cones, the outer cone is fixed, and the inner cone swings eccentrically to crush or break the ore block

(3)
roller crusher: in the gap between two opposite rotating round rollers, the ore block is mainly subject to continuous crushing, but it also has the function of grinding and stripping, and the toothed roller surface also has the function of splitting

(4)
impact crusher: the ore block is broken by the impact of fast rotating moving parts. Belong to this category can be divided into: hammer crusher; Cage crusher; Impact crusher<

(5)
grinding machine: the ore is crushed by the impact and grinding of grinding medium (steel ball, steel bar, gravel or ore block) in the rotating cylinder

(6)
other types of crushing mills: A. roller mill: crushing materials by rotating rollers< B. disc mill: the disc rotation of vertical axis or horizontal axis is used as crushing part
C. centrifugal mill. High speed rotating parts and medium are used to proce centrifugal force to complete crushing
D. vibration mill. High frequency vibration is proced by the rotating shaft, which makes the medium and material collide with each other to complete the crushing effect. All kinds of crushers have different specifications, different scope of use. At present, jaw crusher or rotary cone crusher are mostly used for coarse crushing in concentrator; The standard cone crusher is used for intermediate crushing; Short head cone crusher is used for fine crushing.
