Holding cryptocurrency requires more than leaving funds on an exchange. Setting up your own wallet is strongly recommended. However, with many wallet types available, beginners can feel overwhelmed. This guide explains the major wallet types and how to choose one in 2026.

Hot Wallets vs. Cold Wallets

Wallets 秋季 into two broad categories: hot wallets (always connected to the internet) and cold wallets (managed offline).

Hot wallets come as smartphone apps or browser extensions, convenient for transfers and DeFi use. Cold wallets are hardware devices or paper-based, offering superior security but requiring more effort for transactions.

2026 指南: 如何選擇 a Crypto Exchange and Stay Secure

Choosing the right crypto exchange is the first major decision every crypto investor faces. As of 2026, 日本 has over 20 registered exchanges, each with distinct features. This guide explains how to evaluate exchanges and what security measures you should take as a user.

Exchange Evaluation Criteria

Check Registration

Always verify that the exchange is registered with 日本’s Financial Services Agency (FSA). Operating a crypto exchange without registration is illegal in 日本, and unregistered platforms pose extreme risks. The FSA publishes an updated list of registered operators on its website.

Anti-Hacking: 如何 Use Exchange vs. Hardware Wallets

Sun, 07 Jun 2026 13:15:00 +0900

Because cryptocurrencies are digital assets, they are highly targeted by hackers. Protecting your assets requires understanding the security architecture of exchanges and hardware wallets. We share our guide to self-custody.

The Risks of Keeping Assets on Exchanges (Hot Wallets)

Leaving your crypto inside your exchange account means the exchange controls your private keys (the signature authorizing withdrawals).

Risks: If the exchange gets hacked or faces insolvency, your funds may be frozen or stolen.

What is a Hardware Wallet? (Cold Custody)

A physical USB-like device that manages your private keys completely isolated from the internet (e.g. Ledger, Trezor).

步驟 and 注意事項 to Earn Free Tokens via Airdrops

Mon, 12 Jan 2026 14:35:00 +0900

Web3 projects often reward early users by distributing free tokens via “Airdrops.” While highly lucrative, often yielding thousands of dollars, the field is rife with malicious actors. We outline the mechanics and safety rules.

Why Projects Host Airdrops

Early projects launch token rewards to:

Reward early beta testers and boost app engagement metric targets.
Distribute governance tokens to 社區 nodes, completing the shift to a DAO.

Standard Engagement Tasks

Testing Betas: Connecting wallets to trial early software features.
Liquidity Provision: Staking assets in pools to help establish asset depth.
Social Marketing Tasks: Submitting verification logs after joining 社區 channels.

Crucial Airdrop Scam Countermeasures

Beware of fake Twitter accounts announcing “Airdrop Claim is Live!” Connecting MetaMask to fake sites prompts signature calls that steal all your tokens. Rely strictly on links posted inside verified official Discord channels.

衡量加密貨幣交易所安全標準的清單

Thu, 01 Jan 2026 13:30:00 +0900

選擇加密貨幣交易所時，安全性必須優先於低費用。在過去的周期中，交易所駭客已經消滅了客戶的持倉。我們分享一個評估交易所安全等級的清單。

交易所的5個安全檢查點

1. 冷託管資產比例

有多少客戶資產處於離線狀態？日本金融服務管理局 (FSA) 監管的交易所依法必須將近 100% 的客戶存款冷藏。

2. 多重簽名（Multi-Sig）支持

轉移資金是否需要來自不同授權金鑰的多個簽名？如果單一金鑰洩露，這可以阻止竊賊盜用資金。

3.客戶資金隔離

公司營運資金是否與客戶持有的資金分開？如果交易所申請破產，信託帳戶可以保護客戶資金。

4. 雙重認證 (2FA) 預設值

交易所是否強制使用 Google Authenticator 等應用程式進行登入和提款確認？

5. 即時帳號存取警報

當偵測到來自新 IP 位址或裝置的登入時，應用程式是否會透過電子郵件通知您？
