You don't have to believe in crypto to trade it well. You do have to understand its plumbing — because the leverage, the 24/7 clock and the funding mechanism create behaviours (liquidation cascades, funding squeezes) you simply won't see in stocks or bonds.
8.1What are Bitcoin and Ether?
Bitcoin (BTC) is a fixed-supply digital asset — only 21 million will ever exist, and the issuance rate halves roughly every four years (the "halving"). That hard cap is the core of the "digital gold" / store-of-value thesis. It's increasingly traded as a macro asset: a high-beta, dollar-liquidity-sensitive risk play.
Ether (ETH) is the native asset of the Ethereum network, which runs smart contracts and decentralised applications. ETH is used to pay transaction fees ("gas") and can be staked to help secure the network in exchange for a yield. So ETH behaves a bit like a tech/platform bet with a built-in yield, versus BTC's monetary-asset framing.
8.2What moves crypto?
| Catalyst | Simple reaction | The non-obvious second-order |
|---|---|---|
| Fed easing / ample dollar liquidity | Risk-on → BTC up | Crypto is one of the highest-beta expressions of global liquidity — it often leads the risk cycle, both up and down. |
| Spot-ETF inflows | New demand → price up | ETF flows have made crypto more correlated to traditional risk appetite and to the macro calendar (CPI, FOMC) than in its earlier, more isolated days. |
| The Bitcoin halving | Supply issuance halves → bullish | It's fully known in advance, so the "event" is largely priced; the durable driver is the demand/liquidity backdrop around it, not the date itself. |
| Regulatory crackdown / approval | Down / up respectively | Venue and stablecoin risk can hit price even when the asset's fundamentals are unchanged — an exchange failure is a market-structure shock, not a BTC shock. |
| Over-leveraged longs (high funding) | — | Sets up liquidation cascades: a small drop forces leveraged longs to be liquidated, which pushes price down further, forcing more liquidations. Crashes are amplified by the plumbing (8.4). |
8.3The venue stack — how to actually trade it
Crypto can be traded across a spectrum from fully-regulated and ETF-wrapped to offshore and highly leveraged.
| Vehicle | What it is | Notes |
|---|---|---|
| Spot ETFs | IBIT, FBTC (BTC); ETHA (ETH) | Hold the actual coin; trade in a normal brokerage account. The cleanest regulated exposure for most. |
| CME futures | BTC / MBT; ETH / MET | Regulated, cash-settled futures (full + micro). Used by institutions; basis to spot is tradable. |
| Futures-based ETFs | BITO | Holds CME futures, so it carries roll drag in contango (Part 1.4) — a tracking headwind vs spot. |
| Spot on exchange | Buy the coin directly | Self-custody vs exchange custody; you own the asset but carry venue/custody risk. |
| Perpetual swaps ("perps") | Leveraged derivative, no expiry | The dominant global crypto instrument — and the one with funding (next section). Often offshore. |
Bitcoin alone has at times exceeded $1–2 trillion in market capitalisation, with the total crypto market larger still — comparable to a major commodity complex, though far more volatile. The launch of US spot ETFs in 2024 pulled tens of billions of institutional dollars in and meaningfully changed the market's behaviour and liquidity.

8.4Perpetual swaps, funding & the basis trade
The perpetual swap is crypto's signature instrument: a futures-like contract with no expiry. To keep its price tethered to spot without an expiry to force convergence, it uses a funding rate — a periodic payment between longs and shorts.
When the perp trades above spot (too many longs), funding is positive and longs pay shorts. Suppose funding is 0.01% per 8 hours and you're long $50,000:
Annualised ≈ 0.01% × 3 × 365 = ≈ 10.95% per year cost of being long
Funding is the perp's self-correcting tether: persistently positive funding signals crowded longs (a contrarian warning), persistently negative signals crowded shorts. It's also a real, recurring cost or income you must factor into any held position — ignoring it is a classic rookie leak.
When futures trade above spot (positive basis / contango), you can lock the gap: buy spot, sell the future, and collect the convergence — a market-neutral yield. This is the trade behind much of the institutional ETF/CME flow.
Spot BTC $60,000, 3-month future $61,500 (91 days):
Annualised = 1,500 ÷ 60,000 × (365 ÷ 91) = 0.025 × 4.01 = ≈ 10.0% per year, market-neutral
You're long spot and short the future, so you don't care which way BTC goes — you harvest the basis as it converges to zero at expiry. The risks are funding/financing costs, margin on the short leg, and venue/counterparty risk. When this yield is fat, it tells you the market is paying up heavily for leveraged long exposure.
Crypto never closes, so risk doesn't pause for the weekend — some of the most violent moves happen Saturday night when liquidity is thin and traditional desks are dark. Combine that with the deep leverage available on perps and you get liquidation cascades that overshoot wildly in both directions. The practical implications: size smaller than feels necessary, never run leverage you can't watch, and treat funding and basis as live signals of how crowded the trade has become, not background noise.
