Types of Crypto Wallets and How to Choose: Beginner's Guide 2026

Wed, 08 Jul 2026 10:00:00 +0900

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 fall 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.

Summer 2026 Crypto Market Trends: What Beginners Need to Know

Wed, 01 Jul 2026 10:00:00 +0900

The summer of 2026 is shaping up to be an exciting period for the crypto market. The Bitcoin halving effect is gradually manifesting, and interest rate cuts by major central banks are driving capital into risk assets. This article explains the big picture of the summer 2026 crypto market in terms accessible to beginners.

Three Major Forces Shaping Summer 2026

1. Macroeconomic Shifts

Throughout early 2026, central banks including the US Federal Reserve have shifted to rate-cutting mode, flooding not just equities but also crypto markets with liquidity. In a low-interest environment, yields on deposits and bonds shrink, pushing investor capital toward assets that offer higher potential returns. This trend is expected to accelerate through summer 2026.

Self-Defense Rules to Avoid Failure in Your First Crypto Investment

Mon, 22 Jun 2026 13:45:00 +0900

While offering high gains, crypto markets carry substantial downside risks. To protect yourself from scams and market volatility, we share key self-defense rules for beginners.

Key Self-Defense Rules

1. Invest Only Spare Capital

Crypto is a high-risk asset class that could theoretically drop to zero. Never invest money required for rent, food, or basic living expenses.

The 12-word recovery seed phrase for wallets like MetaMask is the master key to your funds. Anyone who asks for it (including fake support staff) is trying to rob you. Keep it written safely offline.

Anti-Hacking: How to 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).

What are Crypto Assets? Basic Knowledge and Systems for Beginners

Sat, 30 May 2026 13:00:00 +0900

Cryptocurrencies like Bitcoin and Ethereum are daily staples of financial news. While highly watched as investments, few understand their core technology. In this guide, we break down the basics of crypto assets and decentralized networks for absolute beginners.

What is a Crypto Asset?

A crypto asset is a digital currency circulating purely on the internet, secured by advanced cryptography. Unlike fiat currencies (Yen, USD), they do not rely on central banks or national governments to manage them.

Thorough Comparison of Bitcoin (BTC) and Ethereum (ETH)

Tue, 26 May 2026 13:05:00 +0900

Representing the top two crypto assets by market capitalization, Bitcoin (BTC) and Ethereum (ETH) are distinct assets. Though both are cryptocurrencies, their underlying philosophies and use cases are vastly different. We compare these two crypto pillars.

1. Bitcoin (BTC): Digital Gold

Launched in 2009, Bitcoin was engineered as a decentralized, peer-to-peer electronic cash system.

Objective: Store and transfer of value (Digital Gold).
Supply Cap: Strictly capped at 21 million coins, guaranteeing digital scarcity.

2. Ethereum (ETH): Decentralized Supercomputer

Ethereum is a developer platform designed to run decentralized applications and smart contracts.

How Staking Works, Recommended Coins, and Steps for Beginners

Thu, 23 Apr 2026 13:25:00 +0900

Simply holding crypto in your wallet generates zero interest. By utilizing “staking,” you can claim passive yields ranging from 3% to over 10% annually. We explain how staking works and guide beginners on setting it up.

How Staking Works (Proof of Stake)

Assets like Ethereum use the Proof of Stake (PoS) consensus mechanism. By committing (locking) your coins to support the network’s consensus validation, you earn rewards paid in new tokens.

Benefits and How to Start Crypto Accumulation (DCA)

Sat, 11 Apr 2026 13:35:00 +0900

Crypto markets are volatile, and timing purchases is notoriously difficult. The solution is automating purchases using Dollar-Cost Average (DCA). We outline how this strategy reduces risks and how to set it up.

What is Dollar-Cost Averaging (DCA)?

DCA involves buying a fixed fiat amount (e.g., 1,000 JPY) of an asset at set intervals (daily or weekly), regardless of price fluctuations.

When prices are high: You purchase fewer coins.
When prices are low: You automatically purchase more coins.
Goal: Flattens your average cost basis, shielding you from buying local market tops.

Advantages of Crypto DCA

Emotional Stability: Removes the anxiety of timing the market.
Low Start Requirements: Major brokerages support automatic recurring buys starting as low as 100 JPY daily.
Passive Wealth Accumulation: The safest way to capture Bitcoin’s long-term macro trend.

Basic Rules Explained for Crypto Taxes and Tax Returns in Japan

Wed, 01 Apr 2026 13:10:00 +0900

If you generate profits from trading crypto in Japan, understanding taxes and filing returns is mandatory. Japanese tax laws apply distinct rules to crypto that differ from stock trading. We cover the core tax codes to keep you compliant.

Crypto Income is Classified as “Miscellaneous Income”

Under Japanese tax laws, cryptocurrency trading profits are categorized as “Miscellaneous Income” (雑所得) subject to aggregate taxation.

Progressive Tax Rates: The rate climbs with your tax bracket, topping out at a maximum of 55% (combined national income and local inhabitant tax).
No Loss Offset (損益通算): You cannot offset crypto losses against your salary income or stock market profits.

When is Tax Triggered?

Taxes are not triggered by simply holding coins (unrealized gains). Tax liabilities occur upon realization:

Thorough Explanation of Differences between Trading Fees and Spreads

Sun, 08 Mar 2026 13:40:00 +0900

When buying Bitcoin, you might see “Zero Trading Fees” but notice the actual purchase price is higher than the market rate. This is due to “Spreads” (hidden transaction costs). We clarify the difference between trading fees and spreads.

Exchange (板取引) vs. Instant Buy (販売所)

1. Instant Buy (販売所) - High Cost Spreads

You buy directly from the exchange’s personal inventory.

What is Halving? Impact on Bitcoin Price and Historical Data

Sun, 01 Feb 2026 13:20:00 +0900

The primary price cycle of Bitcoin is driven by a programmed event known as the “Halving.” Occurring roughly every four years, we analyze the mechanics of the halving and evaluate historical market cycles.

What is the Bitcoin Halving?

A programmed mechanism inside the Bitcoin protocol that cuts the block rewards issued to network miners in half.

Goal: Prevent currency inflation, preserving digital scarcity (limiting output toward the 21M limit).
Timing: Happens every 210,000 blocks mined (roughly every 4 years).

Historical Cycles: Post-Halving Price Trends

Historically, as the issuance rate of new supply drops, the supply-demand balance triggers a major bull run, typically peaking 12 to 18 months post-halving.

Checklist to Measure the Security Standards of Crypto Exchanges

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

When selecting a cryptocurrency exchange, security must take priority over low fees. In past cycles, exchange hacks have wiped out customer holdings. We share a checklist to evaluate exchange safety levels.

5 Security Checkpoints for Exchanges

1. Percentage of Assets in Cold Custody

How much of customer assets are kept offline? Exchanges regulated by Japan’s FSA are legally mandated to keep near 100% of customer deposits in cold storage.

2. Multi-Signature (Multi-Sig) Support

Does moving funds require multiple signatures from separate authority keys? This stops thieves from draining funds if a single key is leaked.
