However, it's important to be cautious when using these platforms as some may have questionable practices or be scams. Always conduct thorough research before using any service. Here are a few platforms you might consider:

Cointiply: Cointiply is a website that offers various ways to earn Bitcoin, such as watching videos, playing games, and completing surveys. You can withdraw your earnings without making a deposit.
FreeBitco.in: FreeBitco.in is a website where you can earn free Bitcoin through a faucet (a small amount every hour). You can also play games and participate in promotions to earn more.
CryptoTab Browser: CryptoTab Browser is a browser that allows you to mine Bitcoin while you browse the internet. You can withdraw your earnings without a deposit.

Remember to use these websites cautiously, as there are many scams and illegitimate platforms in the crypto space. Verify the legitimacy and reputation of any platform you use, and ensure you understand the risks involved. Additionally, be mindful of withdrawal thresholds and fees, as some platforms may impose limits on how much you can withdraw at a time or charge high fees for transactions.
