When Bitcoin (BTC) introduced decentralized payments in 2008, few predicted that this technology would evolve into a platform for hundreds of diverse applications. Today, from DeFi to GameFi, NFTs, the metaverse, and Web3, blockchain has become the fundamental infrastructure for the digital world. But there is one issue

The blockchain industry has reached an inflection point. After years of focusing on individual chain optimization, the ecosystem is shifting toward interconnected networks. Layer 3 represents this paradigm—not another speed bump for a single blockchain, but rather a framework enabling multiple chain

Understanding the ERC-20 Standard and Its Ecosystem Value
The prosperity of the Ethereum ecosystem relies on the support of the ERC-20 token standard. This standard defines a unified set of rules for creating and interacting with tokens on the Ethereum blockchain, ensuring that all tokens based on this standard are interoperable and compatible.
ERC-20 tokens are not a single asset type; they can represent various digital assets—from cryptocurrencies, utility tokens, and stablecoins to DeFi governance tokens, and even infrastructure for NFTs. This versatility makes ERC-20 one of the most widely used token standards in the Web3 ecosystem.
Because of this, choosing a secure and reliable ERC-20 wallet becomes crucial. It not only concerns the safety of your assets but also impacts your experience in DeFi, governance participation, and Web3 applications.

By December 2025, the exchange rate of the New Taiwan Dollar (NTD) against the Japanese Yen (JPY) reached 4.85, representing an appreciation of over 8% since the beginning of the year at 4.46. Amid rising global risk aversion and expectations of NTD depreciation, purchasing Yen has become more than just a travel preparation; it has become an important option in asset allocation. However, many people end up spending a significant amount—equivalent to several drinks—due to choosing the wrong channels, mainly because of exchange rate spreads and handling fees. This article will delve into the four most practical ways to buy Yen today, helping you find the most cost-effective route.
Why is now a good time to consider buying Yen?
The Japanese Yen has long been regarded as one of the world's three major safe-haven currencies. When market risks increase, large amounts of capital flow into Yen for protection. For example, during the Russia-Ukraine conflict in 2022, the Yen appreciated by 8% within a week, effectively buffering the decline of global stock markets. For Taiwanese investors, purchasing Yen is not only a response to travel needs but also a hedge against fluctuations in the Taiwan stock market.

When the demand on the Bitcoin blockchain exceeds its capacity of 7 transactions per second, problems arise that the ecosystem must address. With the average block creation time set at 10 minutes, network congestion becomes inevitable during periods of high volume.

Proof of Work (PoW) is a Consensus Mechanism that helps distributed networks reach agreement without central management, preventing double spending of digital assets. Miners verify transactions by calculating hash values, ensuring system security. Compared to the emerging Proof of Stake (PoS), PoW has been verified as secure and reliable, forming a Decentralization and immutable Blockchain system.

The cryptocurrency market requires deep knowledge and experience to make a profit.

Hedging in cryptocurrencies is not just a theory, but a real tool for managing risks in a volatile market. If you have digital assets, it is worth understanding how to protect them from unexpected price drops. Today we will look at practical methods of hedging and what to pay attention to for newcomers.

When trading on the Ethereum network, transactions may get stuck due to low Gas fees set. You can speed up or replace the transaction by increasing the Gas fee. Using MetaMask or Trust Wallet can facilitate these operations, but be cautious in setting the Gas price and Nonce value to avoid transaction latency again. Setting the Gas fee reasonably is the best strategy to effectively prevent transaction delays.

We often hear: "I lost money on Bitcoin." But there are ways to reduce these risks.
What does hedging essentially mean?
Hedging is primarily insurance for your assets. Imagine: you have a house in a flood-prone area. You insure it. The logic is the same in cryptocurrency markets — you
