what is the future of Pi Network currency.DOT TECH
The future of the Pi cryptocurrency is uncertain, and its success will depend on several factors. Pi is a relatively new cryptocurrency that aims to be user-friendly and accessible to a wide audience. Here are a few key considerations for its future:
Message: @Pi_vendor_247 on telegram if u want to sell PI COINS.
1. Mainnet Launch: As of my last knowledge update in January 2022, Pi was still in the testnet phase. Its success will depend on a successful transition to a mainnet, where actual transactions can take place.
2. User Adoption: Pi's success will be closely tied to user adoption. The more users who join the network and actively participate, the stronger the ecosystem can become.
3. Utility and Use Cases: For a cryptocurrency to thrive, it must offer utility and practical use cases. The Pi team has talked about various applications, including peer-to-peer transactions, smart contracts, and more. The development and implementation of these features will be essential.
4. Regulatory Environment: The regulatory environment for cryptocurrencies is evolving globally. How Pi navigates and complies with regulations in various jurisdictions will significantly impact its future.
5. Technology Development: The Pi network must continue to develop and improve its technology, security, and scalability to compete with established cryptocurrencies.
6. Community Engagement: The Pi community plays a critical role in its future. Engaged users can help build trust and grow the network.
7. Monetization and Sustainability: The Pi team's monetization strategy, such as fees, partnerships, or other revenue sources, will affect its long-term sustainability.
It's essential to approach Pi or any new cryptocurrency with caution and conduct due diligence. Cryptocurrency investments involve risks, and potential rewards can be uncertain. The success and future of Pi will depend on the collective efforts of its team, community, and the broader cryptocurrency market dynamics. It's advisable to stay updated on Pi's development and follow any updates from the official Pi Network website or announcements from the team.

Financial Assets: Debit vs Equity Securities.pptxWrito-Finance
financial assets represent claim for future benefit or cash. Financial assets are formed by establishing contracts between participants. These financial assets are used for collection of huge amounts of money for business purposes.
Two major Types: Debt Securities and Equity Securities.
Debt Securities are Also known as fixed-income securities or instruments. The type of assets is formed by establishing contracts between investor and issuer of the asset.
• The first type of Debit securities is BONDS. Bonds are issued by corporations and government (both local and national government).
• The second important type of Debit security is NOTES. Apart from similarities associated with notes and bonds, notes have shorter term maturity.
• The 3rd important type of Debit security is TRESURY BILLS. These securities have short-term ranging from three months, six months, and one year. Issuer of such securities are governments.
• Above discussed debit securities are mostly issued by governments and corporations. CERTIFICATE OF DEPOSITS CDs are issued by Banks and Financial Institutions. Risk factor associated with CDs gets reduced when issued by reputable institutions or Banks.
Following are the risk attached with debt securities: Credit risk, interest rate risk and currency risk
There are no fixed maturity dates in such securities, and asset’s value is determined by company’s performance. There are two major types of equity securities: common stock and preferred stock.
Common Stock: These are simple equity securities and bear no complexities which the preferred stock bears. Holders of such securities or instrument have the voting rights when it comes to select the company’s board of director or the business decisions to be made.
Preferred Stock: Preferred stocks are sometime referred to as hybrid securities, because it contains elements of both debit security and equity security. Preferred stock confers ownership rights to security holder that is why it is equity instrument
<a href="https://www.writofinance.com/equity-securities-features-types-risk/" >Equity securities </a> as a whole is used for capital funding for companies. Companies have multiple expenses to cover. Potential growth of company is required in competitive market. So, these securities are used for capital generation, and then uses it for company’s growth.
Concluding remarks
Both are employed in business. Businesses are often established through debit securities, then what is the need for equity securities. Companies have to cover multiple expenses and expansion of business. They can also use equity instruments for repayment of debits. So, there are multiple uses for securities. As an investor, you need tools for analysis. Investment decisions are made by carefully analyzing the market. For better analysis of the stock market, investors often employ financial analysis of companies.

A multitude of models
So we will learn different models for studying
different issues (e.g., unemployment, inflation,
long-run growth).
For each new model, you should keep track of
its assumptions
which variables are endogenous,
which are exogenous

and those it cannot
24. Chapter Summary
Macroeconomics is the study of the economy as
a whole.
Macroeconomists attempt to explain the
economy and to devise policies to improve its
performance.
Economists use different models to examine
different issues.

CHAPTER 1 The Science of Macroeconomics
Gross Domestic Product:
Expenditure and Income
Two definitions:
Total expenditure on domestically-produced
final goods and services.
Total income earned by domestically-located
factors of production.
Expenditure equals income because
every dollar spent by a buyer
becomes income to the seller.

A question for you:
Suppose a firm
produces $10 million worth of final goods
but only sells $9 million worth.
Does this violate the
expenditure = output identity?
41. slide 40
CHAPTER 1 The Science of Macroeconomics
Why output = expenditure
Unsold output goes into inventory,
and is counted as “inventory investment”…
…whether or not the inventory buildup was
intentional.
In effect, we are assuming that
firms purchase their unsold output.

CHAPTER 1 The Science of Macroeconomics
Real GDP controls for inflation
Changes in nominal GDP can be due to:
changes in prices.
changes in quantities of output produced.
Changes in real GDP can only be due to
changes in quantities,
because real GDP is constructed using
constant base-year prices.

Consumer Price Index (CPI)
A measure of the overall level of prices
Published by the Bureau of Labor Statistics
(BLS)
Uses:
tracks changes in the typical household’s
cost of living
adjusts many contracts for inflation
allows comparisons of dollar amounts over time
53. slide 52
CHAPTER 1 The Science of Macroeconomics
How the BLS constructs the CPI
1. Survey consumers to determine composition
of the typical consumer’s “basket” of goods.
2. Every month, collect data on prices of all items
in the basket; compute cost of basket
3. CPI in any month equals
Cost of basket in that month
Cost of basket in base period
100

CHAPTER 1 The Science of Macroeconomics
Reasons why
the CPI may overstate inflation
Substitution bias: The CPI uses fixed weights,
so it cannot reflect consumers’ ability to substitute
toward goods whose relative prices have fallen.
Introduction of new goods: The introduction of
new goods makes consumers better off and, in effect,
increases the real value of the dollar. But it does not
reduce the CPI, because the CPI uses fixed weights.
Unmeasured changes in quality:
Quality improvements increase the value of the dollar,
but are often not fully measured.
58. slide 57
CHAPTER 1 The Science of Macroeconomics
The size of the CPI’s bias
In 1995, a Senate-appointed panel of experts
estimated that the CPI overstates inflation by
about 1.1% per year.
So the BLS made adjustments to reduce the bias.
Now, the CPI’s bias is probably under 1% per
year.

CHAPTER 1 The Science of Macroeconomics
Exercise:
Compute labor force statistics
U.S. adult population by group, June 2007
Number employed = 146.1 million
Number unemployed = 6.9 million
Adult population = 231.7 million
Use the above data to calculate
the labor force
the number of people not in the labor force
the labor force participation rate
the unemployment rate
64. slide 63
CHAPTER 1 The Science of Macroeconomics
Answers:
data: E = 146.1, U = 6.9, POP = 231.7
labor force
L = E +U = 146.1 + 6.9 = 153.0
not in labor force
NILF = POP – L = 231.7 – 153 = 78.7
unemployment rate
U/L x 100% = (6.9/153) x 100% = 4.5%
labor force participation rate
L/POP x 100% = (153/231.7) x 100% = 66.0%
65. Chapter Summary
1. Gross Domestic Product (GDP) measures both
total income and total expenditure on the
economy’s output of goods & services.
2. Nominal GDP values output at current prices;
real GDP values output at constant prices.
Changes in output affect both measures,
but changes in prices only affect nominal GDP.
3. GDP is the sum of consumption, investment,
government purchases, and net exports.

4. The overall level of prices can be measured by
either
the Consumer Price Index (CPI),
the price of a fixed basket of goods
purchased by the typical consumer, or
the GDP deflator,
the ratio of nominal to real GDP
5. The unemployment rate is the fraction of the labor
force that is not employed.
