A plain‑English guide · Updated 2026

Crypto, without the jargon.

Crypto sounds intimidating until you realise it boils down to three questions: why does this exist, how do I get some, and how do I keep it safe. This page answers all three, in plain English, with no shilling and no charts that pretend to predict the future.

SOL-- Ξ ETH-- BTC--
01 · Why crypto

The next payment rail is already here.

Banks still take three business days to move a wire in 2026. Payment processors still freeze accounts on a Sunday afternoon. Card networks still skim 2–3% off every retail transaction in the world. Crypto exists because a piece of software, running on tens of thousands of machines, can do all of that faster, cheaper, and without permission. The next decade of payments is being built on these rails, the only question is whether you're on the network before the rest of the world arrives, or after.

Self-custody

You hold your own money. No bank can freeze it, no processor can reverse the transaction, no government can confiscate it without the keys. Power and responsibility, both yours.

Global & always-on

Send money to anyone, anywhere, on any day, in seconds. No bank holidays, no SWIFT delays, no your card has been blocked for international use phone calls.

Fixed supply

Bitcoin has a hard cap of 21 million coins. No central bank can print more in a panic. For people who watch their fiat lose 3–8% per year to inflation, that scarcity is the entire point.

Open infrastructure

The ledger is public. Anyone can audit it, anyone can build on it. The same rails that move your $20 payment can move a billion-dollar settlement, same fees, same speed, same neutrality.

02 · The three you need to know

Gold, silver, and the payment rail.

Forget the ten thousand alt-coins. The market has settled into a clean three-asset thesis, and once you see it you can't unsee it: Bitcoin is digital gold, the reserve asset. Ethereum is digital silver, the productive, programmable monetary metal. Solana is the payment processor, the rail money actually moves on. Each one solves a different problem, and each is a network we accept at checkout.

The reserve asset. A fixed 21-million supply, no central issuer, sixteen years of unbroken uptime. Every serious balance sheet, sovereign treasuries, public companies, hedge funds, now holds it for the same reason they once held gold: it cannot be diluted. You don't trade it. You stack it.

Bitcoin with a programming language. If BTC is gold, ETH is silver, scarce, monetary, and productive. It runs the smart contracts behind every stablecoin, lending market and tokenised treasury on-chain. Stake it and it pays you a yield in itself. The settlement layer of the internet's financial system.

SOL · The payment rail

The payment processor of crypto. Sub-second finality, fees measured in fractions of a cent, hundreds of millions of transactions a day. This is the rail Visa would have built if it had been designed in 2024. The network of choice when you actually want to use the money, which is exactly why our checkout recommends it.

Stablecoins (USDC, USDT) are a fourth category worth knowing, tokens that track $1 each. They live on the networks above and are how most people park money in crypto without taking on volatility while they wait to deploy capital into the three above.

03 · How to buy

Your first coin, in about ten minutes.

The path from never-owned-crypto to a wallet with SOL in it has gotten dramatically easier. You'll sign up to an exchange, prove who you are, fund the account, and place an order. The whole loop fits in a coffee break.

  1. 1

    Pick an exchange

    Coinbase, Kraken, Crypto.com, Binance, any major regulated exchange in your jurisdiction works. Avoid sketchy off-shore platforms. You're optimising for not getting hacked, not for shaving 0.1% on fees.

  2. 2

    Pass KYC

    Upload an ID and a selfie. This takes 5–20 minutes. It's friction, but it's also the line between a regulated platform and a black-market one. Worth it.

  3. 3

    Fund the account

    Bank transfer is cheapest (free or near-free). Debit card is fastest (instant, 1–3% fee). Credit card is fine but some banks block crypto purchases. Start small, $50 to $200, until you've round-tripped a transfer.

  4. 4

    Place the order

    Use a market order for simplicity. Pick BTC, ETH or SOL, type the dollar amount, hit buy. The coin lands in your exchange account within seconds.

Not your keys, not your coins

Crypto held on an exchange is their crypto, technically. You hold an IOU. For small balances or active trading, that's fine. For anything you actually care about, move it off the exchange to a wallet you control. We'll explain how next.

04 · How to hold

Wallets, seed phrases, and the cardinal rule.

A crypto wallet is just two long numbers: a public address (where people send coins) and a private key (the password that lets you spend them). The private key is usually given to you as a 12 or 24-word backup phrase. Lose it, lose the coins. There is no reset link.

Hot wallet

For spending

An app on your phone or browser. Phantom for Solana, MetaMask for Ethereum, Muun for Bitcoin. Connects to the internet, signs transactions instantly, perfect for everyday use.

  • RiskPhishing & malware
  • Best for< $500 balances
  • CostFree
Cold wallet

For holding

A small hardware device, Ledger, Trezor, Coldcard, that keeps your keys offline. Transactions are signed on the device itself, so even a fully compromised computer can't drain you.

  • RiskPhysical loss
  • Best forLong-term stack
  • Cost$70–$200 one-off
Seed backup

Paper & steel

Write your 12 or 24-word phrase on paper, or stamp it into a steel plate. Store somewhere fire-proof and out of sight. Never photograph it, never type it into a website, never email it to yourself.

  • RiskFire, flood, theft
  • Best forDisaster recovery
  • Cost$0–$80

The seed phrase rules, memorise these

  • Never share it. Not with support staff. Not with us. Not with anyone. Real exchanges and wallet companies will never ask for it.
  • Never type it into a website. If a site asks for your seed phrase, close the tab. You're being phished.
  • Never store it digitally. No cloud notes, no photos, no email drafts. A motivated attacker who breaches your phone or laptop will find it.
  • Test the backup. Before you put real money behind it, wipe the wallet, restore from the phrase, and confirm everything comes back.
05 · How to invest

The 60/30/10 stack beats sitting out.

The most expensive trade in crypto isn't a bad coin pick, it's the decade you spent waiting for a better entry. Bitcoin has compounded at roughly 60% per year since launch; the S&P 500 has done about 10%. You don't need to time the bottom. You need to be in the market, in something boring and broad. The 60/30/10 split below is the boring, broad answer.

The starter portfolio

60 · 30 · 10

One transfer a month, three coins, twenty years of patience. That's the entire strategy. Each slice plays a different role in the stack, gold for the base, silver for the yield, and the payment rail for the upside.

60%

Bitcoin, the digital gold base

Your reserve. The hardest-money asset ever invented and the one institutions buy first. You hold this for the same reason your grandparents held gold bars, it cannot be inflated away. Slow, heavy, irreplaceable.

30%

Ethereum, the digital silver yield

The productive metal. Silver has industrial uses; ETH has on-chain uses, stablecoins, lending, real-world asset tokenisation. Stake it and the network pays you in itself, every block. Faster-moving than BTC, with a similar long-term thesis.

10%

Solana, the payment-rail upside

Higher beta, higher conviction. If crypto becomes the payment layer of the internet, and we think it does, the network that actually settles those payments at sub-second speed is where the asymmetric upside lives. 10% is enough to matter and small enough to sleep through a drawdown.

Rebalance once a year to drift back to the targets. That's it. The portfolio has a name (three-asset stack) and a sample size of every major bull run since 2017. It is not a secret.

1

Being out is the bigger risk

The first instinct of a cautious investor is to wait for clarity. But the longest-running asset class of the 21st century has rewarded presence, not patience, missing the ten best days in BTC over any cycle wipes out most of the return. Small position, in the market, beats large position, on the sidelines.

2

Only invest what you can lose

Crypto is volatile. 50–80% drawdowns happen every cycle. If a total wipe-out would change your life materially, the position is too big. Rent money is not investment money, but neither is leaving 100% of your savings in a currency that loses 3–8% a year to inflation.

3

Dollar-cost average (DCA)

Buy a fixed dollar amount on a fixed schedule, say $100 every Friday, regardless of price. You buy more coins when it's cheap, fewer when it's expensive, and you never have to guess the bottom. DCA is how the boring 60/30/10 stack actually gets built.

4

Stick to 60/30/10

The allocation above isn't arbitrary, it maps to the asset thesis. Gold base, silver yield, payment-rail upside. Avoid exotic alt-coins until you understand why you'd want them; my friend says it'll moon is not a thesis. Boring, broad, hard to mess up.

5

Hold for cycles, not weeks

Bitcoin runs in roughly four-year cycles. Most short-term traders underperform someone who bought and forgot about it. If you can't stomach checking the price once a quarter, you'll panic-sell at the bottom of the cycle and miss the recovery that always follows.

6

No leverage, no rotation

Leverage trading is how 90% of newcomers liquidate themselves. You don't need 10x exposure to an asset that already moves 5% on a Tuesday afternoon. Spot only. And don't rotate, chasing the hot alt today is the most reliable way to underperform the 60/30/10 stack you started with.

DCA vs. lump-sum, quick math

Same $1,200, invested differently across one year of Bitcoin volatility. The DCA outcome is duller, smaller in good years, and dramatically better in bad ones, which is the whole point.

Lump-sum

Put $1,200 in on day one. If it goes up, you win big. If it crashes 50% the next month, you stare at $600 for a year.

Interactive calculator

Run the numbers on your own DCA plan.

Pick a monthly contribution and a holding window. We project the outcome across three scenarios, a bear case (10% annualised), a base case (25% annualised, roughly the post-2017 BTC average smoothed for cycles), and a bull case (45% annualised). All three are below BTC's lifetime CAGR. None of them are predictions, they're a back-of-the-envelope sanity check.

Projections assume monthly contributions compounding at the stated annualised rate. They are mathematical illustrations, not forecasts, future returns can and will diverge from history. Past performance is not indicative of future results.

Long-horizon price targets

Where could Bitcoin land?

A scenario table for context, not certainty. The numbers below are derived from a starting price of $95,000 compounded at the same three annualised rates as the calculator (10% bear, 25% base, 45% bull). They illustrate why showing up monthly for ten or twenty years tends to dominate trying to call the next swing trade.

Year Bear · 10%/yr Base · 25%/yr Bull · 45%/yr
2026$104,500$118,750$137,750
2027$115,000$148,400$199,700
2028$126,400$185,500$289,500
2030$152,950$289,800$609,000
2035$246,300$884,700$3.91M
2040$396,700$2.70M$25.07M
2045$638,900$8.24M$160.79M

These are compounding-curve scenarios from a $95,000 anchor, not analyst forecasts. The bull track in particular implies a market cap that would rival or exceed gold, possible, not promised. The point of the table is the shape, not the digits: time in the market dominates timing the market.

06 · Common mistakes

How people lose their stack.

Almost every crypto horror story is one of about six mistakes, repeated over and over. Read these once and you've immunised yourself against most of them.

07 · Glossary

DCA
Dollar-cost averaging. Buying a fixed amount on a fixed schedule to smooth out price volatility.
Self-custody
Holding your own private keys instead of trusting an exchange to hold them for you.
Seed phrase
A 12 or 24-word backup that fully reconstructs your wallet on any device.
Hot wallet
