EPISODE 108 — What Is Liquidity — and Why It Matters in Crypto

Liquidity is the most important property of any financial market — and one of the least understood by beginners in crypto. It is the reason you can sell one Bitcoin instantly at close to the quoted price. It is also the reason that attempting to sell a large position in a low-volume altcoin can cost you 20% or more in slippage before the order is half filled. It is the reason that DeFi protocols can have billions in TVL and still be vulnerable to catastrophic cascades when market conditions change rapidly. Every financial decision in crypto is affected by liquidity — and understanding it changes how you approach position sizing, token selection, and risk management.

In this episode of Crypto for Beginners, we explain liquidity in full. We start with market liquidity: what bid-ask spread actually measures, what order book depth reveals about how much can be bought or sold without moving the price significantly, and how to use trading volume as a practical proxy for whether a token is safe to build a significant position in. We explain slippage — the gap between the expected price and the actual execution price from insufficient order depth — and how to estimate it before placing a large trade using DEX aggregators.

We then explain DeFi liquidity specifically: how automated market makers work, what liquidity providers actually do when they deposit into pools, how trading fees are distributed proportionally to pool contributors, and what the economic logic of providing liquidity looks like. We cover impermanent loss in full technical detail: the mathematical relationship between asset price changes and LP position value, why it is realised only on withdrawal, and how to assess whether fee income for a given pool historically exceeds impermanent loss. We cover how liquidity evaporates during market stress — the negative feedback loop between price decline, liquidity withdrawal, and forced liquidations — and what this means for position sizing.

EPISODE 107 — Sei Network — The Chain Built for Trading

Most blockchain projects build a general-purpose platform and then hope traders will come. Sei made a different decision: it built everything — the consensus mechanism, the transaction processing model, the native order matching engine, the fee structure — specifically around the requirements of financial trading applications. In 2026, its Giga upgrade is targeting 200,000 transactions per second with sub-400 millisecond finality — a performance profile that would make it the fastest blockchain in existence by a significant margin.

In this episode of Crypto for Beginners, we explain Sei Network comprehensively. We cover the three architectural choices that make Sei purpose-built for trading: parallel transaction execution, which allows independent transactions to be processed simultaneously rather than sequentially; the built-in order matching engine at the consensus layer, which reduces matching latency below what any smart-contract-level matching can achieve; and sub-400ms finality that is essential for applications where outdated price information causes real losses. We explain why these choices give trading applications structural advantages over equivalent functionality on general-purpose chains like Solana or Ethereum.

We explain the Giga upgrade in detail: what the Autobahn multi-proposer consensus mechanism is, how separating data availability agreement from full block download enables the throughput jump to 200,000 TPS, and what this level of performance would actually enable in terms of applications and use cases that are currently impossible on any chain. We cover Sei's growing gaming ecosystem and Q3 2025 gaming transaction records. We explain the Wyoming stablecoin pilot recognition as a signal of institutional interest. We cover the SEI token: its supply structure, nine-year vesting schedule, staking mechanics, and how the Giga announcement moved markets.

EPISODE 106 — What Is a Hard Fork — When Blockchains Split

On August 1, 2017, the Bitcoin blockchain permanently divided into two chains. Every person who held Bitcoin at that moment suddenly held the same amount of Bitcoin and Bitcoin Cash simultaneously — their keys worked on both chains, both tokens had real market value, and years of bitter community debate had finally ended in a permanent split. In 2026, Bitcoin faces another potential fork — and for the first time, the question of what happens to forked coins involves not just individual holders but BlackRock, Fidelity, MicroStrategy, and the regulated custodians holding millions of Bitcoin for institutional clients.

In this episode of Crypto for Beginners, we explain what a hard fork is and everything it implies. We cover the technical mechanics: what it means for blockchain software rules to be incompatible, how nodes on different versions end up maintaining separate chains, and what determines which chain survives long-term — primarily which version attracts miners or validators, exchange listings, and developer support. We explain the crucial difference between hard forks and soft forks: what backward compatibility means and why SegWit could be implemented without splitting Bitcoin while the block size increase could not.

We tell the full story of the Bitcoin Cash fork: the scaling debate, the two camps, the August 2017 split, and what happened to both chains in the years that followed. We then cover the Ethereum Classic fork — a fundamentally different kind of split driven by philosophical values about immutability rather than technical disagreement — and what the choice to reverse the DAO hack revealed. We cover the planned 2026 Bitcoin eCash fork in full: what Drivechains are, why Paul Sztorc is forcing the issue through a competing chain rather than the upgrade process, and what the implications are for ETF sponsors, corporate Bitcoin treasuries, and individual holders during crypto's most institutionalised era.
