There are three honest ways to end up with crypto you did not buy. They get talked about as one thing — "free crypto" — which is why people chase the one with the worst odds and skip the one that actually pays.
They are not variations of the same offer. They differ in what they cost you, and the cost is never money: it is time, or capital you have to already have, or custody of your coins. This guide sets them side by side on that basis, and says which one to start with.
Airdrops: the largest payouts, and the worst odds
Airdrops are what people picture. The numbers are real and they are enormous — Uniswap distributed roughly $6.4 billion, and any wallet that had used the protocol received 400 UNI, worth about $1,400 at launch and over $16,000 per wallet at the market peak. Hyperliquid distributed $1.8 billion on a single day.
What the numbers hide is the denominator. Those rewards went to people who had used the platforms months or years before any token was announced, for their own reasons, with no promise of anything. The snapshot is always taken before the announcement — which means by the time an airdrop is something you have heard about, the decision that qualified people for it was made long ago.
That does not make airdrops worthless. It makes them a by-product rather than a strategy: use platforms you would use anyway, keep the wallet you used them with, and occasionally something arrives. Treating it as an income plan is how people end up spending months farming protocols that never issue a token.
Staking: small, steady, and the only one that scales
Staking pays you for locking coins that help secure a proof-of-stake network. The yield is modest by design — it comes from newly issued supply, not from a company's profits — and it is the only one of the three that scales with how much you hold. Ten times the stake is ten times the reward, which is not true of an airdrop or a sign-up bonus.
The cost is custody and, on locked terms, liquidity. Stake through an exchange and the coins sit with the platform; take the higher locked rate and you cannot sell during the term, which bites hardest in exactly the weeks you would want to. Flexible terms pay less and cost you almost nothing in optionality.
It is the right route for coins you were going to hold through a cycle anyway. It is a poor reason to buy a coin you would not otherwise own.
Sign-up rewards: the only one with a floor
This is the route people skip because it sounds too ordinary, and it is the only one of the three where doing the work reliably produces the reward. Exchanges pay for new verified accounts because a funded account is worth more to them than the bonus costs. The tasks are specified in advance — register, verify identity, deposit, place a first trade — and completing them pays out.
The honest limits: the headline figure is a maximum, not a payout. A "$30,000 bonus" is a tiered programme unlocked through deposit size and trading volume, and most people will unlock the first tiers and stop. The parts with a genuine floor are the small fixed rewards — MEXC pays 20 USDT for signing up, before any deposit, and a $500 gold-token position for completing identity verification. Those are the ones you can count on.
One rule decides whether you get any of it: the referral code has to be entered when the account is created. Exchanges fix eligibility at that moment and cannot attach a bonus to an account afterwards. It is the single most common way people lose a reward they had already earned.
The fee discount nobody counts as free crypto
The least exciting benefit is the one that compounds. Registering through a referral link takes 20% off standard trading fees at Bybit, OKX, Bitget and Gate.io, permanently, on every trade you ever make. MEXC charges 0% on spot outright.
Run the arithmetic once and it stops looking boring. At the industry-standard 0.10%, someone trading $50,000 of spot volume a month pays $600 a year in fees. A 20% discount returns $120 of that annually, and 0% returns all of it — every year, without a task to complete or a snapshot to be in. Over a few years that quietly beats most sign-up bonuses, and it is the only one of these benefits that cannot be forfeited by missing a deadline.
What to ignore
Anything that asks for a private key or seed phrase is theft, without exception — no legitimate reward has ever needed one. Anything that asks you to send crypto to "unlock" or "activate" a reward is theft; free things do not require payment. A site created a few days ago, or a project with no verifiable presence beyond the airdrop announcement, is the same thing wearing a better website.
Faucets and click-to-earn apps are not scams, they are just a poor trade: they pay cents for hours. If your time is worth anything at all, the ten minutes it takes to open an account with a sign-up reward pays better than a month of them.
Where to start
In order of certainty: take the sign-up rewards on one or two exchanges you would actually use, because they have a floor and take minutes. Stake the coins you already hold on flexible terms, because you were holding them anyway. Then let airdrops happen to you rather than chasing them, by using platforms early for reasons that would stand up even if no token ever appeared.
For picking the first account, the deciding factor should be the exchange rather than the bonus — you will be living with the fees and the interface long after the reward is spent. Our comparisons cover that in detail, and the codes on this site apply the discount at sign-up.
