Are there any no-deposit crypto sign-up bonuses?

Not quite, among major exchanges right now. OKX's bonus — previously the closest thing to a true no-deposit offer, with a $10 KYC-only step — now requires a minimum $1 deposit to unlock its first $5 tier. That's about as low a bar as you'll find, though: most other bonuses on this page, including Coinbase, Kraken and Gemini's referral rewards, require a $50–$100+ deposit or trade to qualify.

How to get free crypto without paying?

There are several legitimate ways to earn free crypto without spending money. Many exchanges award a small crypto bonus when you sign up as a new customer, and some platforms pay you to watch short lessons and pass simple quizzes — programs like Coinbase Earn work this way. Airdrops are another option, where blockchain projects distribute free tokens to early supporters, though participation sometimes requires holding a specific asset or paying network fees to claim, so they aren't always truly free. Crypto faucets — websites that give away tiny amounts of cryptocurrency in exchange for simple tasks like solving captchas or watching ads — are also an option, though they're best treated as a learning tool rather than a serious income stream.

Can you make $100 a day with Bitcoin?

It's technically possible, but far from guaranteed. Making $100 a day trading Bitcoin is possible, but it is not simple, fast, or guaranteed — and feasibility is directly tied to how much capital you're starting with, since the more capital you have, the smaller the percentage gain needed to hit the target. Focusing on a fixed daily dollar amount may not be the best approach, as trading is a marathon rather than a sprint — the key to success is concentrating on average performance over the long term rather than daily wins.
