Watching liquidation levels can be a useful part of a scalping strategy for bitcoin. When a trader has a large leveraged position and the price of bitcoin moves against them, their position may be "liquidated" if it falls below a certain level, known as the liquidation price. If this happens, the trader will be required to sell their position to close it out, potentially at a loss.

By monitoring the liquidation levels of other traders, a scalper can potentially identify opportunities to buy or sell based on the potential for other traders' positions to be liquidated. For example, if a trader sees that a large position is close to being liquidated, they may decide to buy in anticipation of a price rebound once the position is closed out. However, it's important to keep in mind that this is a risky approach and can lead to significant losses if the market doesn't move in the expected direction.

Crypto investors, be like Scrooge McDuck!

Scrooge McDuck is a character created by Disney in 1947. He is a wealthy duck who is known for his love of money and his miserly ways. Despite his flaws, however, Scrooge is also a clever and resourceful character who is willing to do whatever it takes to protect his fortune. He is also fiercely independent and determined, qualities that make him an admirable and inspiring figure.

For many people, Scrooge McDuck represents the ultimate embodiment of the American Dream. He started out with nothing, but through hard work and determination, he was able to build a massive fortune for himself. He is a self-made man who is not afraid to take risks in order to achieve his goals.

Despite his love of money, Scrooge is also a generous and kind-hearted individual. He is willing to help those in need, and has even been known to put his own safety on the line in order to protect those he cares about. In this way, he is a true hero, and someone who we can all look up to.

Another reason why Scrooge McDuck is my spirit animal is because of his unwavering determination and resilience. No matter how many obstacles he faces, Scrooge never gives up. He is always willing to try again, even if it means facing failure. This kind of determination is something that we can all learn from, and is something that can help us to achieve our own goals and dreams.

Ultimately, Scrooge McDuck is a complex and layered character who embodies many different qualities that we can all admire and aspire to. He may be a bit of a miser, but he is also fiercely independent, determined, and generous. These are all traits that make him an inspiring and admirable figure, and someone who we can all look up to.

Here's a small introduction to Solidity! Check it out!

Solidity is a high-level, statically-typed programming language used for implementing smart contracts on the Ethereum blockchain. It was developed by the Ethereum Foundation, and is the most popular language for writing smart contracts on Ethereum.

Solidity is an object-oriented, high-level language that was designed to be similar to popular programming languages like JavaScript and C++. It is statically-typed, which means that all variables must be declared with their types before they can be used in the code. This helps to prevent type errors and enables the compiler to catch more errors at compile time.

One of the key features of Solidity is that it allows developers to create their own custom data types. This is useful for representing complex data structures, such as arrays, structs, and mappings. For example, the following code defines a struct that represents a simple user profile:

struct UserProfile {

string name;

uint age;

bool isVerified;

}

In this code, the UserProfile struct has three fields: name, age, and isVerified. The string type represents a sequence of characters, the uint type represents a positive integer, and the bool type represents a boolean value (i.e., true or false).

Solidity also provides a number of built-in data types that are commonly used in smart contracts. For instance, the address type represents the Ethereum address of a contract or account. The uint type (which stands for "unsigned integer") represents a non-negative integer, and the bytes32 type represents a fixed-size byte array.

In addition to data types, Solidity also provides a number of built-in functions and operators that can be used in smart contracts. For example, the keccak256 function is used to compute the Keccak-256 hash of a given value. The transfer function is used to send Ether from one account to another, and the require function is used to enforce preconditions in a contract.

Here is an example of a simple Solidity contract that demonstrates some of these features:

pragma solidity ^0.5.0;

contract SimpleContract {

// Define a struct to represent a user profile

struct UserProfile {

string name;

uint age;

bool isVerified;

}

// Create a mapping from user addresses to user profiles

mapping(address => UserProfile) public userProfiles;

// Function to create a new user profile

function createUserProfile(string memory _name, uint _age, bool _isVerified) public {

// Create a new user profile

UserProfile memory profile = UserProfile(_name, _age, _isVerified);

// Save the user profile in the mapping

userProfiles[msg.sender] = profile;

}

// Function to retrieve a user profile

function getUserProfile(address _user) public view returns (string memory, uint, bool) {

// Retrieve the user profile from the mapping

UserProfile memory profile = userProfiles[_user];

// Return the user profile fields

return (profile.name, profile.age, profile.isVerified);

}

}

In this contract, the createUserProfile function allows users to create a new user profile by providing their name, age, and verification status.

How cool are L2s? Let's dig in and find out!

Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. These apps run on a custom built blockchain, an enormously powerful shared global infrastructure that can move value around and represent the ownership of property.

One key aspect of the Ethereum platform is its use of L2, or Layer 2, protocols. L2 protocols are built on top of the Ethereum blockchain and are designed to improve scalability, security, and privacy for dApps (decentralized applications) built on Ethereum. In this article, we will explore some of the key advantages of using L2 protocols on the Ethereum platform.

First and foremost, L2 protocols improve scalability. The Ethereum blockchain is capable of processing only a limited number of transactions per second, which can be a major bottleneck for dApps with high throughput requirements. L2 protocols, on the other hand, can handle a much larger number of transactions per second, allowing dApps to scale more efficiently and serve more users.

For example, the popular L2 protocol known as Plasma allows dApps to process transactions off-chain, which significantly reduces the burden on the Ethereum blockchain. This means that dApps built on Plasma can handle more transactions per second, resulting in faster and more efficient operations.

In addition to improving scalability, L2 protocols also enhance security. Because L2 protocols operate on top of the Ethereum blockchain, they inherit the security of the underlying blockchain. This means that dApps built on L2 protocols are protected against many of the security threats that plague other blockchain platforms, such as 51% attacks, double spending, and frontrunning.

Furthermore, L2 protocols can also provide additional security features, such as fraud proofs and challenges, which can help to prevent malicious actors from exploiting vulnerabilities in dApps. This added layer of security is especially important for dApps that handle sensitive data or manage valuable assets, as it can help to prevent data breaches and other security incidents.

Another advantage of L2 protocols is that they can improve privacy for dApps. Because L2 protocols operate off-chain, they can provide greater privacy for dApps by hiding transaction data from the Ethereum blockchain. This is especially useful for dApps that need to protect the privacy of their users, such as those that handle personal data or confidential information.

For instance, the L2 protocol known as Zero-Knowledge proofs (ZKPs) allows dApps to prove the validity of a transaction without revealing any sensitive data. This means that dApps built on ZKPs can provide strong privacy protections for their users, while still being able to prove the validity of their transactions on the Ethereum blockchain.

Overall, L2 protocols provide a number of key advantages for dApps built on the Ethereum platform. They improve scalability, enhance security, and provide improved privacy for dApps, making them a valuable tool for developers building on Ethereum. As the use of L2 protocols continues to grow, we can expect to see more and more dApps leveraging their benefits to deliver faster, more efficient, and more secure services to their users.
