This document introduces the concepts of risk-neutral valuation and derivative pricing. It defines derivative securities as contracts contingent on the value of an underlying asset. The key questions in pricing derivatives are determining the expected payoff and the information required to calculate it. The document explains how replication arguments and preventing arbitrage opportunities can be used to derive fair prices for forwards, calls, puts and other derivatives under the risk-neutral measure, where the expected return on the underlying asset is equal to the risk-free rate. Relaxing simplifying assumptions, more advanced stochastic models can also be used for risk-neutral pricing.

how can I sell my pi coins for cash in a pi APPDOT TECH
You can't sell your pi coins in the pi network app. because it is not listed yet on any exchange.
The only way you can sell is by trading your pi coins with an investor (a person looking forward to hold massive amounts of pi coins before mainnet launch) .
You don't need to meet the investor directly all the trades are done with a pi vendor/merchant (a person that buys the pi coins from miners and resell it to investors)

how can I sell pi coins after successfully completing KYCDOT TECH
Pi coins is not launched yet in any exchange 💱 this means it's not swappable, the current pi displaying on coin market cap is the iou version of pi. And you can learn all about that on my previous post.
RIGHT NOW THE ONLY WAY you can sell pi coins is through verified pi merchants. A pi merchant is someone who buys pi coins and resell them to exchanges and crypto whales. Looking forward to hold massive quantities of pi coins before the mainnet launch.
This is because pi network is not doing any pre-sale or ico offerings, the only way to get my coins is from buying from miners. So a merchant facilitates the transactions between the miners and these exchanges holding pi.
I and my friends has sold more than 6000 pi coins successfully with this method. I will be happy to share the contact of my personal pi merchant. The one i trade with, if you have your own merchant you can trade with them. For those who are new.
Message: @Pi_vendor_247 on telegram.
I wouldn't advise you selling all percentage of the pi coins. Leave at least a before so its a win win during open mainnet. Have a nice day pioneers ♥️

when will pi network coin be available on crypto exchange.DOT TECH
There is no set date for when Pi coins will enter the market.
However, the developers are working hard to get them released as soon as possible.
Once they are available, users will be able to exchange other cryptocurrencies for Pi coins on designated exchanges.
But for now the only way to sell your pi coins is through verified pi vendor.
Here is the telegram contact of my personal pi vendor

how to swap pi coins to foreign currency withdrawable.DOT TECH
As of my last update, Pi is still in the testing phase and is not tradable on any exchanges.
However, Pi Network has announced plans to launch its Testnet and Mainnet in the future, which may include listing Pi on exchanges.
The current method for selling pi coins involves exchanging them with a pi vendor who purchases pi coins for investment reasons.
If you want to sell your pi coins, reach out to a pi vendor and sell them to anyone looking to sell pi coins from any country around the globe.
Below is the contact information for my personal pi vendor.

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.
Introduction to Indian Financial System ()Avanish Goel
The financial system of a country is an important tool for economic development of the country, as it helps in creation of wealth by linking savings with investments.
It facilitates the flow of funds form the households (savers) to business firms (investors) to aid in wealth creation and development of both the parties
Currently pi network is not tradable on binance or any other exchange because we are still in the enclosed mainnet.
Right now the only way to sell pi coins is by trading with a verified merchant.
What is a pi merchant?
A pi merchant is someone verified by pi network team and allowed to barter pi coins for goods and services.
Since pi network is not doing any pre-sale The only way exchanges like binance/huobi or crypto whales can get pi is by buying from miners. And a merchant stands in between the exchanges and the miners.

2. WHAT ARE DERIVATIVE SECURITIES ?
• Fundamental Securities – eg: stocks and bonds
• Derivative Securities - Contract between two parties
• The contract specifies a contingent future financial claim
• Contingent on the value of a fundamental security
• The fundamental security is refered to as the underlying
asset
• A simple example – A binary option
• How much would you pay to own this binary option ?
• Key question: What is the expected payoff ?
• What information is reqd to figure out the expected payoff
?
4. A CASINO GAME
• The game operator tosses a fair coin
• You win Rs. 100 if it’s a HEAD and 0 is it’s a TAIL
• How much should you pay to play this game ?
• Would you rather play a game where you get Rs. 50 for both H & T ?
• What if you get Rs. 1 Crore for H and Rs. 0 for T ?
• Depends on your risk attitude
• Risk-averse or Risk-neutral or Risk-seeking
• What is the risk premium for a risk-averse individual ?

6. LAW OF DIMINISHING MARGINAL UTILITY
• Note that the total utility function f(x) is concave
• Let x (qty of consumption) be uncertain (some probability distribution)
• Then, E[ f(x) ] < f( E[x] ) (Jensen’s inequality)
• Expected Utility is less than Utility at Expected Consumption
• Consumption y that gives you the expected utility: f(y) = E[ f(x) ]
• So, when faced with uncertain consumption x, we will pay y < E[x]
7. LAW OF DMU RISK-AVERSION
• E[x] is called the expected value
• y is called the “certainty equivalent”
• y – E[x] is called the “risk premium”
• y – E[x] depends on the utility concavity and distribution
variance
• More concavity means more risk premium and more risk-
aversion
• So to play a game with an uncertain payoff, people would
Generally pay less than the expected payoff
8. A SIMPLE DERIVATIVE – FORWARD CONTRACT
• Contract between two parties X and Y
• X promises to deliver an asset to Y at a future point in time t
• Y promises to pay X an amount of Rs. F at the same time t
• Contract made at time 0 and value of F also established at
time 0
• F is called the forward price of the asset
• What is the fair value of F ?
• Expectation-based pricing to arrive at the value of F is
wrong

Asset price at time t
10. TIME VALUE OF MONEY
• The concept of risk-free interest rate is very important
• Deposit Rs. 1 and get back Rs. 1+r at time t (rate r for time
t)
• So, Rs. X today is worth Rs. X*(1+r) in time t
• If I’ll have Rs. Y at time t, it is worth Rs. Y/(1+r) today
• So you have to discount future wealth when valuing them
today
• With continuously compound interest, er instead of (1+r)
11. ARBITRAGE
• The concept of arbitrage is also very important
• Zero wealth today (at time 0)
• Positive wealth in at least one future state of the world (at
time t)
• Negative wealth in no future state of the world (at time t)
• So, starting with 0 wealth, you can guarantee positive
wealth
• Arbitrage = Riskless profit at zero cost
• Fundamental concept: Arbitrage cannot exist in financial
12. USE THESE CONCEPTS TO VALUE A FORWARD
• Contract: At time t, you have to deliver asset A and receive Rs. F
• Assume today’s (t = 0) price of asset A = Rs. S
• Step 1: At time 0, borrow Rs. S for time t
• Step 2: At time 0, buy one unit of asset A
• Step 3: At time t, deliver asset A as per contract
• Step 4: At time t, receive Rs. F as per contract
• Step 5: Use the Rs. F to return Rs. Sert of borrowed money
• If F > Sert , you have made riskless money out of nowhere
• Make similar arbitrage argument for your counterparty
• Arbitrage forces F to be equal to Sert
13. REPLICATING PORTFOLIO FOR A FORWARD
• A Forward can be replicated by fundamental securities
• Fundamental Securities are the Asset and Bonds
• “Long Forward”: At time t, Receive Asset & Pay Forward Price
F
• “Long Asset”: Owner of 1 unit of asset
• “Long Bond”: Lend money for time t (receiving back Rs.1 at t)
• “Short positions” are the other side (opposite) of “Long
positions”
• “Long Forward” equivalent to [“Long 1 Asset”, “Short F
Bonds”]
• Because they both have exactly the same payoff at time t
• This is called the Replicating Portfolio for a forward
14. DERIVATIVES: CALL AND PUT OPTIONS
• X writes and sells a call option contract to Y at time 0
• At time t, Y can buy the underlying asset at a “strike price” of K
• Y does not have the obligation to buy at time t (only an “option”)
• So if time t price of asset < K, Y can “just ignore the option”
• But if time t price > K, Y makes a profit at time t
• At time 0, Y pays X Rs. C (the price of the call option)
• With put option, Y can sell the asset at a strike price of K
• What is the fair value of C (call) and of P (put) ?

16. PRICING OF OPTIONS
• Again, it is tempting to do expectation-based pricing
• This requires you to know the time t distribution of asset
price
• We know expectation-based pricing is not the right price
• Note that Call Payoff – Put Payoff = Fwd Payoff when K = F
•This is useful but doesn’t help us in figuring out prices C and
P
• Like forwards, use replication and arbitrage arguments
• However, replication is a bit more complicated here
• Consider two states of the world at time t
20. WHAT EXACTLY HAVE WE DONE HERE ?
• We have altered the time t asset price’s mean to F = Sert
• Arbitrage-pricing is equiv to expected payoff with altered mean
• Altered mean corresponds to asset price growth at rate r
• But bond price also grows at rate r
• All derivatives are replicated with underlying asset and a bond
• So, all derivatives (in this altered world) grow at rate r
• In reality, risky assets must grow at rate > r (Risk-Aversion)
• Only in an imaginary “risk-neutral” world, everything will grow at
rate r
• But magically, arbitrage-pricing is equivalent to:
Expectation-based pricing but with “risk-neutrality”
assumption
21. RELAXING SIMPLIFYING ASSUMPTIONS
• Model a stochastic process for underlying asset price
• For example, Black Scholes: dS = μS dt + σ S dW
• Use Girsanov’s Theorem to alter process to “risk-neutral
measure” Q
• Risk-neutral Black Scholes process: dS = r S dt + σ S dWQ
•Bond process is: dB = r B dt
• Two-state transition works only for infinitesimal time dt
• So, expand into a binary (or binomial) tree to extend to time t
• Use “backward induction” from time t back to time 0
• At every backward induction step, do discounted expectation
• But using risk-neutral probabilities (derived from repl.
portfolio)
22. CONTINUOUS-TIME THEORY: MARTINGALE PRICING
• One has to assume the replicating portfolio is “self-financing”
• Any profits/losses are reinvested into the next step’s repl.
portfolio
• Underlying asset and its derivatives have a drift rate of r (in Q)
• So, discounted (by e-rt ) derivatives processes have no drift
(no dt term)
• Driftless processes are martingales
• So, in the risk-neutral measure, the martingale property is
used to
