Frequently Asked Questions

Q: What is the purpose of the app?

A: To have fun. Just try some random number(can be a really big number too) and if you are very very VERY lucky, maybe you can find some free bitcoin or sats sitting in those addresses.

Q: If I find some BTC, can I send it to my address?

A: Sure. Just generate a transaction with required information(from, to, amount, fee), sign and send it to bitcoin network.

Q: Is it ok to enter my addresses's secret number?

A: NO. Never neither enter nor keep your private key, secret or 24 word seeds online. Use a cold wallet.

Q: Is it ok to use adresses that I found as my receiving address for my bitcoin transactions?

A: NO. Never use those addresses for your transactions. To receive bitcoin, always generate new addresses from seed words/cold wallet.

Q: How does it work?

A: A random number(private key) between 1 and 2²⁵⁶ is used in an elliptic curve multiplication, a one-way cryptographic function, to generate a public key. From the public, we use a one-way cryptographic hash function to generate a bitcoin address.(from the book "Mastering Bitcoin")
