1  Other / Beginners & Help / [Tip / Info to Newbies] No Payment id required for Monero(XMR) wallet address on: December 11, 2019, 10:46:24 AM
After the Monero hard fork on Nov. 30th, there are few changes and upgrades done. The new upgrade introduced the Proof-of-Work algorithm, RandomX which uses random code execution together with memory-focused techniques to be resistant to application-specific integrated circuits (ASIC) — devices optimized for professional mining operations.

Also, the long payment id has been removed. The exchanges have made the integrated XMR address mandatory.


For the users who do not know what is an Integrated address, I am briefing it for them -

The integrated address is an address with an embedded payment id. Payment ID in a transaction will be encrypted with a shared secret (one-time random key known only to the sender and recipient). Only the recipient will be able to match the transaction against payment ID.

The integrated address does not contain an extra id like the standard address where it was using the 32 bytes payment id along with the address.

The standard public address is made of:

Quote
network byte 18 + public spend key + public view key + checksum

The integrated public address is made of:

Quote
network byte 19 + public spend key + public view key + 64-bit payment ID + checksum

Now all the users should use integrated Monero addresses as the exchanges made the use of integrated addresses mandatory. There is no need for a payment id for the XMR address like before.

2  Alternate cryptocurrencies / Speculation (Altcoins) / Why VeChain(VET) pumped 65% this month? on: November 15, 2019, 11:30:37 AM
VeChain has shown it's strength by increasing from it's all time low price. The other altcoins are showing the similar price action, like ZRX(0x) was the first coin to breakout from it's longterm downtrend. For the first time since listing, VeChain managed to break the 200-day exponential moving average (EMA), as can be seen in the following chart.

It’s not only moving above the 200-DMA and EMA, but it also broke a 14-month long downtrend.


>> What could be the reason for the price of VeChain and Volume to increase?

3  Economy / Trading Discussion / Auto-Trader Feature for Crypto Purchases on: November 06, 2019, 10:50:49 AM
Recently, I read an article where an Australian crypto exchange Independent Reserve has introduced the "AutoTrader" feature for its clients to purchase their crypocurrencies automatically. This feature will allow customers to set automated rules and strategies for trading cryptocurrency. Also, it includes scheduled bank transfers, which would allow customers to dollar cost average (DCA) their cryptocurrency purchases.

Quote from: CEO of Independent Reserve
“Autotrader allows users to buy smaller parcels of cryptocurrency at regular intervals, for example daily or weekly or monthly. This limits their exposure to price fluctuations, especially compared to customers that may enter the market in a large way, and then see the market move against them,” the CEO stated.


My question: If we use AutoTrading feature, will it really benefit us? Anyone who is using that feature can share your experience here?
4  Economy / Trading Discussion / Basic Crypto Trading Strategies for New Digital Asset Investors on: October 25, 2019, 10:37:26 AM
Most crypto trading strategies will include technical analysis, so if you aren’t familiar with this, then you need to start studying. Technical analysis can work in these markets, but you need to be quick in your analysis, and decisive in your trades.

Along with some technical analysis, it is good if you know some trading strategies. Some of the basic Cryptocurrency Trading Strategies are:

Swing Trading

Swing trading is a popular cryptocurrency trading strategy that depends heavily on technical analysis.

If you want to become a successful swing trader you’ll need a good grasp of chart analysis. It will help you get a feel for market movements and can help you identify significant price movements before they happen.

Swing traders need to have the discipline to determine entry and exit points and stick to them without getting caught up in emotions.

If you employ a swing trading strategy you might only place several trades a week, but each trade should have the potential for great profits.


Day Trading

Day trading is a fast-paced and sometimes stressful trading strategy, where positions are held for no more than a single day.

The day trader might use leverage when trading to amplify gains since they are closing out all of their trades by the end of each trading session.

Day trading is about sharp decision making and the ability to manage risk. It is also about the ability to take a win or a loss equally without emotion and move to the next trade.


Arbitrage Trading

Arbitrage trading is (usually) an algorithmic trading strategy that has been quite popular in cryptocurrency trading circles.

Arbitrage involves taking advantage of price differences between exchanges. With so many cryptocurrency exchanges, these pricing anomalies are fairly common.

Arbitrage trades might take less than a second when using a bot, and the profit could be $1 or less, but the strength of this strategy is that the bot can conduct hundreds of these trades each day, and the small profits can add up to sizable profits.


HODLing

“HODLing” is the quintessential long-term crypto trading strategy that anyone can use. It is good for beginners because it requires little skill and no trading experience.

The fundamental strategy behind hodl is to identify a digital asset that has long-term potential, buy that asset, and then hold it securely until it appreciates in value significantly.

One thing to keep in mind with a hodl strategy is that you can sell some parts of your holdings to lock in profits.


Apart from these basic strategies, there are more advanced strategies you can explore.

5  Bitcoin / Bitcoin Discussion / World’s first offline system for transacting cryptocurrencies! on: September 20, 2019, 11:51:39 AM
Recently, I was reading this news that Israeli cybersecurity startup GK8 has developed the first system that enable the blockchain transactions without the need for an Internet!! How can this be Possible?

Well the new system uses GK8’s proprietary cryptographic techniques that enables the transactions to get executed without Internet. The company raised $4 million in a funding round led by Discount Capital, a venture arm of one of Israel’s three largest banks, Discount Bank, and Marius Nacht, a co-founder of cybersecurity giant Checkpoint.

As reported by Globes, GK8’s new cryptographic techniques allowed the company to develop a cold wallet with “hot wallet functionalities,” securing user funds from hackers and cyberattacks.

GK8 is currently targeting financial institutions, custodians, exchanges and hedge funds which hold cryptocurrencies. GK8's custodian technology is already operational and helps to securely manage digital assets for clients such as eToro, a global multi-asset trading and investment platform.

Current custodian solutions used by financial institutions and state-owned enterprises do not meet institutional scale security standards. In addition to existing security protocols, digital assets based on blockchain technology need a higher security standard since signed transactions are irreversible. To meet this challenge, GK8 experts have developed this technique to provide a secure environment to sign blockchain transactions and execute automatic reconciliation confidently.

The company’s techniques, protected by five registered patents, can bypass core assumptions related to cryptocurrency transfers and eliminate attack vectors to any asset transfer.


>> My question here - Is this technique is really secure than the current solutions? Is our funds are safe from hackers and cyberattacks?


Edit:

I gathered few more information where I found a Video by one of the board members of GK8, and one of the founding scientists of Zcash token, Prof. Eran Tromer explained that -

Quote
The company’s cold wallet offering has "unidirectional communication" from the wallet. It never accepts raw information back into the wallet from the outside. “This minimizes the attack surface and prevents attacks,” he said.

--> Check this Video by Prof. Eran Tromer


Also, a patent abstract associated with Lamesh described the technology as follows:

Quote
“The digital wallet device is electronically disconnected from other digital devices and comprising: a cryptocurrency integrated circuit (IC) that is isolated from any computer interface” … “and a unidirectional communication hardware for sending said transaction to a communication device for broadcasting said transaction via a network.”

6  Other / Beginners & Help / Missing Out The Important Topics!! on: August 29, 2019, 05:20:45 AM
I am using the Bitcoin forum from quiet a few days and I felt many of them are missing out the useful and important topics on this forum. Why do people usually check the threads that are on the 1st page of any Bitcointalk section and comment on those threads only. Even I have realised lately that there are many important threads which we are missing out in this forum. There should be some method or feature which should make the visibility of these threads on top.

Some of the useful threads which are important and I felt that we are missing out are:


Edit:

Not only this there are hundreds of Topics which we are missing out daily. There should be some place where all these information should be stored and available for all the Newbies. I would request the community members to add the topic which they find very important and useful for the users. Even I will update it frequently. Thank you!
7  Alternate cryptocurrencies / Altcoin Discussion / How to create your own cryptocurrency? on: August 27, 2019, 05:02:59 AM
I was reading an article about how to create our own cryptocurrency. I felt this article would help many crypto enthusiasts who are looking to create their own crptocurrency.

We usually buy cryptocurrencies on any crypto exchange and hold it in our wallet or exchange wallet. We never thought of creating our own cryptocurrency. How this will benefit us?


Let's see how we can create our own cryptocurrency -

Step 1: Create your own cryptocurrency

To create your own crypto, you would either have to build your own blockchain or use a cryptocurrency creation platform. If you own customized blockchain then you will have control over your cryptocurrency. There are many ‘create your own cryptocurrency’ courses available but it costs you a lot.

Also, you can use modern method of making cryptocurrencies where a cryptocurrency creation platform do the technical part for you. This is the fast method but involve initial costs.

Apart from these, the best and the free method of creating your own cryptocurrency is to use existing open-source code from any existing platform and changing it as per your preferences. This is the best method if you don’t have a lot of money. This requires very simple coding which you can easily learn by watching a good tutorial on YouTube.

Step 2: How to make money with your coins and how to secure them?

These steps are often difficult than the creation part and most people fail in this market because they don’t follow them.
An altcoin doesn’t start making money right away.In order to ensure this for your coin, you have to be active within a local crypto community. In fact, you should do this even before you actually make your coin. The secret to a successful altcoin is that it actually meets the needs of its local community.

Step 3: Coin performance

Your cryptocurrency, no matter how well it is coded, is basically useless until people are willing to verify the transactions made with it. For this, you’d have to look for miners on the network. Make sure you build up a good relationship with the miners you connect with so that you gain their trust. Properly communicate the idea behind your coin and also the purpose of the same.

Step 4: Ensure safety and reliability of a coin

For that, you’d have to have a basic understanding of the ways of the hackers. You must do a substantial amount of research on these topics and ensure that your cryptocurrency has as a fewer loopholes.


**Some of the benefits of having your own cryptocurrency are it's lower operational cost, transaction anonymity, elimination of fraud risk and accessibility to a whole new customer base.

8  Other / Beginners & Help / What is Coinbase Transaction? on: August 22, 2019, 11:41:53 AM
A Coinbase transaction is a unique bitcoin transaction that is created by the miners to collect block rewards. And any transaction fees collected by the miners are also sent in this transaction. It is the first transaction in a New block.

  • When a miner creates a candidate block, the first space for a transaction is reserved for the coinbase transaction.

  • The main difference between normal transaction data and Coinbase transaction is it has no inputs and there is one created with each new block that is mined on the network. This transaction is called as "Coinbase"

  • One interesting point is that the "first Coinbase Transaction cannot be spent".There are some theories behind it. The issue here is that the original transaction was not placed in the unspent transaction outputs. Although you can find the transaction in the blockchain, there is no way to spend bitcoins that cannot be found in the transaction database.

  • The bitcoins from a Coinbase transaction can be spent only after it has 100 confirmations in the blockchain. This is to safeguard to prevent outputs that originate from the coinbase transaction from becoming unspendable

  • Also, you need to make sure that the sum of your output values does not exceed the block reward + transaction fees you're collecting.


>> I found this information very informative and useful. If anyone knows more about this can share your thoughts here.

9  Other / Beginners & Help / How to identify Crypto Scams? on: August 17, 2019, 05:05:06 PM
Many users are attracted to the crypto market for acquiring massive returns on their investments. There are many cryptocurrencies in the market, it is tough to identify the good ones from the bad ones. Scammers will be waiting for the opportunity to scam the users. It is important to know which is a good cryptocurrency to invest and what not to invest?

Some of the common characteristics of crypto Scams are:
  • Absence of Key information
  • Unrealistic claims and
  • No codebase


1) Absence of Key information like "No WhitePaper" and "Absence of team members info". It is important to check the white paper information of any coin. Also, information about the founders and developers team of a crypto should be found, if not then it is a doubtful project.

2) Unrealistic claims: Some of the common fraudulent schemes in the cryptocurrency community that promotes unrealistic claims includes Cloud Mining Services, Bitcoin Investment Packages, and Multi-level marketing.
 
  • Cloud Mining Services: Many fraudulent cloud mining websites offer Bitcoin mining operations to earn mining rewards by just providing initial capital upfront without investing in your own computing hardware.

  • Bitcoin Investment Packages (BIPs): BIPs are high-yielding investment programs that promise high returns with small payout structures. Due to some scam projects, BIPs have limited life.

  • Multi-level marketing schemes: MLM scheme offers referral schemes promoting cryptocurrency investments and users will easily get trapped by this.

3) Non-Existence Of Code Base: Majority of the cryptocurrencies are Open-sources and not all coins that are closed-source are scams. But all coins that have been branded as scams do not reveal their code base or simply doesn’t have them.


I read an article and felt that there are many crypto scams running around us which many users are not aware of. Please share your experience about the scams which you have come across and what all methods you use to identify a crypto scam?

10  Economy / Trading Discussion / What is MACD(Moving Average Convergence Divergence)? How to use it? on: August 10, 2019, 01:14:48 PM
Moving average convergence divergence(MACD) is a technical indicator that shows the relationship between 2 moving averages of prices. MACD helps investors to understand whether the bullish or bearish movement in the price is strengthening or weakening.

There is a formula to calculate MACD -

Quote
MACD = 12 Period EMA - 26 period EMA




The 2 commonly used Moving Averages are:

  • Simple Moving Average = Average price of crypto/specific time period = price of crypto for 7 days/7(Example)
  • Exponential Moving Average(EMA): It is calculated based on the latest price data. It reacts to the recent price changes. MACD uses EMA.



Three Components of MACD




1) MACD Line (Blue): It is the differnec between long term EMA(26 period EMA) with short term EMA(12 period EMA).
2) Single Line(Orange): The 9 day EMA of MACD is called "signal" which is plotted on top of MACD line to trigger buy and sell signals.
3) Histogram: The difference between MACD line and Signle Line with passage of time. If the MACD is above the signal line, the histogram will be above the MACD’s baseline. If the MACD is below its signal line, the histogram will be below the MACD’s baseline. Traders use the MACD’s histogram to identify when bullish or bearish momentum is high.


Now Let's see how to use MACD in Trade

There are 2 indicators which we can use to check for buying and selling.
1. Center/Zero Line Crossover
2. Signal Line Crossover

1. Center/Zero Line Crossover: Two important points to be noted here are:
Quote
  • When MACD line crosses above the Zero Line = BUY
  • When it crosses below the Zero Line = SELL





Positive signal: If the MACD line is above the centre line then it is a positive signal.This occurs when the 12-day EMA is higher than the 26-day EMA. In this case, the prices tend to move upwards.

Negative signal: When the MACD line is below the centre line, it is a Negative signal. In this case, price move further downwards.


2. Signal Line Crossover:
Quote
  • When MACD line crosses above the Signal Line = BUY
  • When it crosses below the Signal Line = SELL





Bullish Crossover: It is positive signal that occurs when MACD line crosses over the Signal line in upward fashion. In this period, the prices sores high.

Bearish Crossover: It is negative signal that occurs when MACD line crosses below the signal line.In this period, the prices will drop low.


How to use MACD in trading view?

Step 1: Click on the indicator "~"
Step 2: Search MACD and select the indicator


 

>> I hope this post will help many Newbies and those who do not know how to look at charts for buying and selling. Please share what all methods and parameters do you check while trading? Is this one of the methods do you check while trading?

11  Other / Beginners & Help / Different Bitcoin Address Formats on: August 05, 2019, 11:53:04 AM
I was reading about different address formats of Bitcoin and I felt many of the Newbies will not know the different address formats of Bitcoin. In fact, even I didn't know that there are multiple address formats we can choose from.

There are 3 Bitcoin address formats:

  • P2PKH or Legacy Address Format
  • P2SH addresses
  • Bech32 Address format

P2PKH Address: Is nothing but Pay-to-Pubkey hash which means pay to the hash of recipient address. If the address is starting with a number "1", for example, "1BVXXXXXXXX", then you are using a P2PKH or Legacy Address, which is the original Bitcoin address format.

P2SH address format: These are the addresses which start with "3", for example, "3j9XXXXXXXXXXX". P2SH stands for Pay to script hash which has more functionality than legacy addresses. P2SH script functions are used where multiple digital signatures are required to authorize the transaction.

Bech32 Address: This address is completely different from the other 2 addresses. This address starts with "bc1", example: "bc1XXXXXXXXX". It's a native segwit address which is supported by most of the wallets but it is not supported by most of the exchanges.

Additional to this, Bitcoin Cash(BCH) supports both Legacy format(addr starting with '1') and Cash Address format which is based on bech32, starting with 'q' or 'bitcoincash:q'. Also, there is a converter tool(https://cashaddr.bitcoincash.org/) to switch between the address formats.

It is important to know which wallet and exchanges support which address formats and choose the address which is supported by most of them. Please let me know which all wallets and exchanges support different address formats. Also, I would like to know the type of addresses you are using?

12  Bitcoin / Bitcoin Discussion / BitCoin : The Money of People on: July 09, 2019, 11:11:01 AM
I was reading the "Internet of Money" by Andreas M Antonopolus and here is an excerpt from the book -

Quote
“Approximately 1 billion people currently have access to banking, credit, and international finance capabilities—primarily the upper classes, the Western nations. Six and a half billion people on this planet have no connection to the world of money. They operate in cash-based societies with very little access to international resources. They don’t need banks. Two billion of these people are already on the internet. With a simple application download, they can immediately become participants in an international economy, using an international currency that can be transmitted anywhere with no fees and no government controls. They can connect to a world of international finance that is completely peer-to-peer. Bitcoin is the money of the people.

At its center are simple mathematical rules that everyone agrees on and no one controls. The possibility of connecting these 6 1/2 billion people”
“to the rest of the world is truly revolutionary.”


“Payment processors are going to be affected. These enormous companies charge higher fees to send money to poorer destination countries, a situation that is exploitative and corrupt. These organizations make enormous profits for a function that can be done in bitcoin nearly for free. As the adage of the entire internet once went, “I just replaced your entire industry with 100 lines of Python code,” that’s exactly what we’re doing with bitcoin.”
Excerpt From: Andreas M. Antonopoulos. “The Internet of Money”. Apple Books.

*Note - I have the e copy of the book, and it's a must read for beginners. You can message me and I will share it across.

14  Other / Beginners & Help / What is DAO? How DAO's work? on: June 04, 2019, 11:37:37 AM
The main idea behind DAO or a Decentralized Autonomous Organization is establishing a company or an organization that can fully function without hierarchical management. Any autonomous organization with a decentralized governance and budgeting system can be called a DAO.

The idea of such management model has been in the cryptocurrency community since Bitcoin managed to get rid of middlemen in financial transactions.
Examples of such community using DAO's are: Dash Cryptocurrency, BitShares etc.

How DAO'S work?

Bitcoin was considered to be the first ever fully-functional DAO, as it has a pre-programmed set of rules.

There are set of rules according to which it will operate. Those rules are encoded as a smart contract, which is essentially a computer program, that autonomously exists on the Internet, but at the same time it needs people to perform task that it can’t do by itself.

Once the rules are established, a DAO enters a funding phase. Firstly, a DAO has to have some kind of an internal property tokens that can be spent by the organization or used to reward certain activities within it. Secondly, by investing in a DAO, users get voting rights and subsequently the ability to influence the way it operates.

Advantages of DAOs

Every innovative idea can be put forward by anyone and considered by the entire organization, as there’s no hierarchical structure. A set of pre-written rules that every investor is aware of before joining the organization as well as the voting system leave no room for quarreling whatsoever.

DAOs are completely transparent, every single financial transaction, are recorded in the Blockchain, available for review to anyone.


>> What are your thoughts about DAO's?  Should this model be followed by every cryptocurrency or exchanges?
