According to financial news ,The world's largest investment fund, BlackRock, (NYSE: BLK), is considering an investment of $ 5.4 trillion ($ 5.4 trillion) in the encroachment market. There are a lot of huge investment funds that are planning to enter the crypto market. This will help the market change in the near future .

Cryptocurrency has a great possibility that everyone wants to have it. It is anonymity and potential economic power. Cryptocurrency is always full of storms and stands before it.
The power of money is something too powerful and it is very real. If you have money then you can buy everything and live in rich. It can be used against the government
In that bitcoin was created to resist the overthrow of power and it would last forever without being manipulated by anyone.
You can not find the source of the money in the crypto but you can find out the source of the money you use in life.

You will be more at risk and the trend will increase with many times if you do not have much knowledge about it. That also happens in the cryptographic market. People have given up the advice of experts and plunged into the market, leaving them at risk and losing money. You should learn more to reduce your risk. This gives you more peace of mind when investing

POW：(Proof of Work) is a requirement to define an expensive computer calculation, also called mining, that needs to be performed in order to create a new group of trust less transactions (the so-called block) on a distributed ledger called blockchain. mainly is based on computation power, it means you are as powerful as the number(and power) of your CPUs.

POS: (Proof of stake) so another algorithm was developed that works completely different and makes you powerful as your stakes, in another word the amount of the coins that you earn is related to amount of stakes that you hold, for example, if you have 10% of a coin in your account, you would earn 10% of new coins that are created in future(the concept is simplified, there are more details in technical terms) because the probability of you signing next block would be related to your amount of stake. in this case you don't need to solve very hard mathematical challenges anymore which prevents wasting many resources like electricity, and also if someone wants to own more than 51% of the stakes to do the attack, he/she has to buy 51% of the stakes which is practically impossible because when he/she starts buying all the coins, the price would go to the moon and he/she won't be able to afford all that money.

You think positively and that will contribute to changing the world. Cryptocurrency has provided people with financial satisfaction and where payment is a core issue. Cryptocurrency and blockchain are now being Enterprises apply to help their work be promoted more vigorously

The issue of moving fast and some exchanges being closed, is simply blocking a group of people trying to access. To avoid this, we can only rely on decentralized exchanges.
This means that the exchange only works on the controlled smart contract

Profitability of cryptocurrency is decreasing, leading to reduced hardware demand and the GPU may drop to 20% next month. Hardware manufacturers are turning to gamers, so the number of graphics cards is expected to decrease in the coming months. So if anyone has the money can buy the machine at the time, if the market grows stronger. At present, the company is also launching discounts and promotions to expel the remaining shipments, so investment is now quite safe if you have a positive mind about the market, the level of risk Also, the current PoW protocol is being gradually replaced by many protocols such as NEO's dBFT mechanism, PoS protocol, Masternodes, and these protocols. It does not need to be handled with a digger, depending on the protocol. The operation mechanism has a separate authentication algorithm, so it does not need a digger, does not require power, the use of existing resources is very large. Keep Coins in your wallet for active investors. Therefore poW in the future will gradually be replaced. All investment decisions must be carefully calculated to avoid risk.

I have a point of view like this:
- If a project develops on the NEO platform, then they have to spend about $ 500 GAS around 5-6k $ and these projects are very popular. In addition, the project team will work seriously. The majority of projects like this are not easy to become garbage
- Projects that are developed on the basis of ERC20 are now too much and that distorts the market. While making a smart contract on ETH Network is extremely easy and cost only $ 1. This is too easy to create phishing projects.
I will prioritize a project developed on the NEO platform instead of a project on the ERC20

Vitalik Buterin, in an interview with TechCrunch, wished centralized crypto-exchanges: "Burn in hell as much as possible." And apparently kind and shy
Saturday's news:
Chinese crypto business in chocolate. The head of the Binance Exchange, Changpeng Zhao, forecasts $ 1 billion in profits in 2018. And the cost of a manufacturer of equipment for mining Bitmain is up to $ 12 billion

Any computer system wants to be free from the possibility of hacker attacks, especially if the service is related to money.

So, the main problem is: proof of stake is safer than proof of work?

Experts are worried about it, and there are several skeptics in the community.

Using a Proof-of-Work system, bad actors are cut out thanks to technological and economic disincentives.

In fact, programming an attack to a PoW network is very expensive, and you would need more money than you can be able to steal.

Instead, the underlying PoS algorithm must be as bulletproof as possible because, without especially penalties, a proof of stake-based network could be cheaper to attack.

To solve this issue, Buterin created the Casper protocol, designing an algorithm that can use the set some circumstances under which a bad validator might lose their deposit.

He explained: “Economic finality is accomplished in Casper by requiring validators to submit deposits to participate, and taking away their deposits if the protocol determines that they acted in some way that violates some set of rules (‘slashing conditions’).”

Slashing conditions refer to the circumstances above or laws that a user is not supposed to break.
