How Crypto Trading Works: Exchanges, Futures and Leverage
Crypto trading works by buying and selling digital assets such as Bitcoin and Ethereum on an exchange, where your orders are matched against other traders' orders in an order book. You can trade the coin itself (spot) or contracts based on its price (futures, perpetuals and options). Markets run 24/7, prices move fast, and leverage multiplies both gains and losses.
The basics: what you're actually trading
A cryptocurrency is a digital asset recorded on a blockchain. When you "trade crypto", you are doing one of two things:
- Buying the coin itself (spot). You pay, say, ₹50,000 and own that much Bitcoin. If the price rises 10%, your holding is worth ₹55,000.
- Trading a contract on its price (derivatives). You don't own the coin; you hold a contract whose value follows the coin. This lets you go short (profit if the price falls) and use leverage.
The idea is the same as in any market: buy lower than you sell. What differs is how the market is built.
How crypto exchanges work
The order book
Every exchange keeps an order book for each trading pair, such as BTC/USDT or BTC/INR. It is two lists:
| Side | What it holds | Example |
|---|---|---|
| Bids | Buy orders, highest price first | Buy 0.05 BTC at 60,000 |
| Asks | Sell orders, lowest price first | Sell 0.05 BTC at 60,020 |
The gap between the best bid and the best ask is the spread. When a buy order meets a sell order at the same price, a trade happens, and that trade sets the latest price.
Market and limit orders
- Market order: "fill me now at the best available price". Fast, but in a thin market you can get a worse price than you expected (slippage).
- Limit order: "fill me only at this price or better". You control the price, but the order may not fill.
Liquidity and market makers
Liquidity is how much you can trade without moving the price. Market makers keep placing buy and sell orders on both sides, which keeps spreads tight. Bitcoin and Ethereum are usually liquid; small altcoins often aren't, so a single large order can move their price a lot.
Many exchanges, many prices
There is no single central exchange for crypto. The same coin trades on many exchanges at once, and prices can differ slightly between them. That is where arbitrage ideas come from, though the gaps are usually small and close quickly.
Types of crypto trading
Spot trading
You buy and own the coin. No leverage, no expiry, and the most you can lose is what you paid. Best for beginners and longer-term holders.
Futures
A futures contract is an agreement on a coin's price with a set expiry date. You put up margin (a fraction of the contract value), can go long or short, and gains or losses are settled in the contract.
Perpetual futures
Perpetuals are futures with no expiry, the most traded crypto derivative. To keep their price close to the spot price, longs and shorts pay each other a funding rate at fixed intervals (often every eight hours). If you hold a position for days, funding becomes a real cost or income.
Options
A call option gives the right to buy at a set price; a put gives the right to sell. Some crypto exchanges, including Delta Exchange, list Bitcoin and Ethereum options with daily, weekly and monthly expiries. Options let you define risk (a bought option can lose only its premium) or collect premium by selling, which carries larger risk.
Margin trading
You borrow to trade a bigger position than your own money covers. Leverage works the same way on futures and perpetuals.
How leverage really works
Leverage is the part of crypto trading that most often goes wrong. At 10x leverage, ₹10,000 of margin controls a ₹1,00,000 position. A 1% move in the coin is a 10% gain or loss on your margin.
Approximate move against you that wipes out your margin at each leverage level
In practice the exchange liquidates you before your margin reaches zero, because it keeps a maintenance margin buffer. So the real distance is a little smaller than the chart shows.
What moves crypto prices
- Supply and demand on exchanges, including large holders buying or selling.
- Regulation and tax news in major markets, including India.
- Macro factors such as interest rates and risk appetite in global markets.
- Leverage itself: when many leveraged positions are liquidated together, forced selling (or buying) can make a move much sharper.
- Sentiment and news, including social media. Crypto reacts to headlines faster than most markets.
Crypto vs stock trading at a glance
| Crypto | Indian stocks | |
|---|---|---|
| Trading hours | 24 hours, 7 days | Weekdays, 9:15 am to 3:30 pm |
| Venue | Many independent exchanges | NSE and BSE |
| Regulation | Taxed, but no SEBI framework for crypto | Regulated by SEBI |
| Volatility | Usually much higher | Lower, with circuit limits |
| Tax on gains | 30% flat, 1% TDS, no loss set-off | Depends on holding period |
Crypto tax in India in brief
India taxes gains from virtual digital assets, including crypto, at a flat 30% (plus cess) under Section 115BBH, and 1% TDS applies on transfers above the threshold under Section 194S. Losses on one crypto trade can't be set off against other income, or carried forward. Tax rules change, so check the current position with a tax adviser before you trade actively.
Managing risk in a market that never closes
Crypto's biggest risk is not one bad trade; it is a bad trade at 3 am with no exit. A few rules every crypto trader should have:
- Set the exit before the entry. Decide the stop-loss price before you buy or sell.
- Keep leverage low. Make sure your stop is hit well before the liquidation price.
- Cap the daily loss. Stop trading for the day after a fixed loss, for example 2% of your capital.
- Use exchanges you've checked. In India, look for exchanges registered with FIU-IND, and turn on two-factor authentication.
- Size positions small. Crypto's volatility means a "normal" position in stocks is often too big in crypto.
Automating crypto trading
Because the market never closes, many crypto traders put their rules into an algorithm that watches the price for them and exits on schedule. If you're choosing which rules to automate, start with the best algorithm for crypto trading and the best trading strategy for crypto.
Frequently asked questions
How does crypto trading work for beginners?
You open an account on a crypto exchange, complete KYC, add funds, and place buy or sell orders. The exchange matches your order with another trader's through its order book. Beginners usually start with spot trading, where you own the coin and there is no leverage.
Is crypto trading legal in India?
Yes, buying, selling and holding crypto is legal in India, but it is not regulated like stocks. Gains are taxed at 30% with 1% TDS on transfers, and exchanges serving Indian users must register with FIU-IND.
What is the difference between spot and futures in crypto?
In spot trading you buy and own the coin. In futures you trade a contract on the coin's price, usually with leverage, and you can go short. Futures can lose more than you'd expect because leverage multiplies every move.
What is a perpetual contract in crypto?
A perpetual is a futures contract with no expiry date. A funding payment between buyers and sellers at regular intervals keeps its price close to the spot price.
Can crypto trading be automated?
Yes. You can turn your entry, exit and stop-loss rules into an algorithm that runs around the clock on a connected exchange. Test it on past data and in a test mode before using real money.
Why is crypto more volatile than stocks?
Crypto markets are younger, trade around the clock, have no circuit limits, and use a lot of leverage. Forced liquidations of leveraged positions can turn an ordinary move into a sharp one.
