Common Questions

Frequently Asked

Real answers to questions everyone has when starting out

Is Bitcoin safe?
+
The Bitcoin network itself has never been hacked in its 15+ year history. The math behind it is extremely secure. However, individual users can lose Bitcoin if they lose their private keys or fall for scams. Think of it like cash—the dollar is safe, but you can still lose your wallet. Keep your keys secure, use reputable services, and you'll be fine.
Do I need to buy a whole Bitcoin?
+
Not at all! Bitcoin is divisible to 8 decimal places. You can buy $10, $50, or any amount you're comfortable with. The smallest unit (0.00000001 BTC) is called a "satoshi." Most people start small and learn as they go.
Where does Bitcoin come from?
+
New Bitcoin is created through "mining"—computers solving complex puzzles to verify transactions. As a reward, miners receive newly created Bitcoin. This happens automatically about every 10 minutes. The total supply is capped at 21 million Bitcoin, with the last one expected to be mined around 2140.
Can I lose my Bitcoin?
+
Yes, if you lose access to your private keys (like forgetting a password with no recovery option). This is why backups are crucial. Many people write down their "seed phrase" (a series of words that can restore their wallet) and store it somewhere very safe. If you keep Bitcoin on an exchange, losing access to that account could also mean losing your Bitcoin.
Is Bitcoin anonymous?
+
Bitcoin is "pseudonymous," not anonymous. All transactions are public on the blockchain, but they're linked to addresses (random strings of characters) rather than names. However, once an address is connected to your identity (like through an exchange), your transaction history can be traced. It's more transparent than private.
