What are Bitcoin Faucets?

In the early days of Bitcoin, an innovative concept called bitcoin faucets was created to increase adoption. These faucets dispensed small amounts of BTC to anyone willing to claim it, similar to product sampling in the physical world. The first faucet, created by Gavin Andresen in 2010, gave away 5 BTC (now worth over $250,000!) to anyone who completed a simple captcha.

Today, bitcoin faucets still exist, allowing users to earn small amounts of BTC by completing tasks like watching videos or solving puzzles. While the rewards are much smaller than in the past, they can still add up over time. For example, a faucet might dispense $0.0017 worth of BTC per hour, which may not seem like much, but can accumulate to a withdrawable amount over several days or weeks.

Bitcoin faucets are important because they provide an easy way for newcomers to enter the cryptocurrency space, learn about Bitcoin, and start building their crypto portfolio. They also promote engagement and awareness about cryptocurrency, which can lead to increased adoption and growth. So, while the rewards may not be life-changing, bitcoin faucets offer a fun and accessible way to get started with crypto.

The Secret of Bitcoin Mixers

Bitcoin mixers, also known as tumblers, allow users to anonymize their Bitcoin transactions. While Bitcoin was initially seen as a way to make anonymous payments online, its public blockchain can reveal transaction histories. KYC regulations further complicate privacy. Bitcoin mixers address this by rerouting transactions through complex networks, making it harder to trace the original sender and recipient.

Users send their coins to a mixer, which blends them with other transactions. This breaks the link between the sender and the recipient. For example, coins sent from Wallet #W are first directed to a mixer at Wallet #X, mixed with other coins, and then sent to Wallet #Y before finally reaching the recipient at Wallet #Z. This process ensures there’s no direct connection between Wallets #W and #Z. Note that a small fee (0.25%-3%) is deducted for the service.

Types of Bitcoin Mixers

- Centralized Mixers: Centralized or custodial mixers are third-party services that mix Bitcoin transactions. While straightforward and often cheaper, they have significant drawbacks: they can log users' transaction details and may be compelled to share these logs with authorities. There’s also a risk of the service refusing to return funds.

- Decentralized Mixers: Decentralized or non-custodial mixers use smart contracts or protocols like CoinJoin to mix transactions without a third party. They pool transactions from many users and redistribute the funds, ensuring privacy without keeping logs. However, they can be complex and require many users to function efficiently.

Bitcoin mixers can be misused for illegal activities, making it difficult for law enforcement to track criminals. High fees and the risk of services closing down and taking users' coins are additional concerns.

Filter Files By Size

Let's imagine a situation where a site is taking a long time to load in your browser and you realize the files are too big.

Well, how do you know precisely what size those files are? The standard developer tools also have a little-known filter.

In order to use it you have to indicate "larger-than:N" in the "Network" tab, where you should indicate the minimum size of the file instead of "N".

Here you can see the value of 100000 bytes, which is equivalent to 100 kilobytes. You can specify your own values, for example "100kb" or "0.1mb".

How to Build Web Apps Prototypes?

The Clutch platform guides you from the design phase to its implementation. The tool allows to use ready-made components (e.g., feedback boxes, user avatars, etc.).

You can mix and match components for optimal results, and create libraries out of them. Using pre-made solutions reduces development time. Further, the created prototype can be tested on different platforms and devices.

How to Check an Image for Copyright?

The topic appears as complicated as any picture has a copyright, but with different licenses for use.

Normally, the copyright is indicated by a watermark or metadata with the author's signature.
