Acquiring Bitcoin can be done through exchanges or decentralized platforms, but caution must be exercised when sharing personal information on regulated platforms.
To hold Bitcoin securely, mobile wallets like Blue Wallet or Samurai Wallet can generate seed words that need to be securely stored, while hardware wallets like Foundation Passport or Coldcard provide added offline security.
Running a Bitcoin node with software like Bitcoin Core or plug-and-play options like Ronin Dojo can enable users to verify their own transactions and reduce dependence on centralized nodes.
CoinJoin implementations like JoinMarket and Wasabi Wallet enhance privacy by combining multiple Bitcoin transactions into a single transaction, making it difficult to trace the original transactions.
Efficient UTXO management using tools like Coin Control helps enhance privacy, reduce transaction fees, and optimize the overall storage of Bitcoin by allowing users to choose which UTXOs to include in transactions.
Deep dives
Acquiring Bitcoin and holding keys
To acquire Bitcoin, individuals can use exchanges or peer-to-peer decentralized exchanges like BISC or HODL HODL. It is important to be cautious about sharing personal information on regulated platforms, as they are vulnerable to hacks. Holding Bitcoin securely involves using mobile wallets like Blue Wallet or Samurai Wallet, which generate 12 or 24 seed words that must be securely stored. For added security, individuals can consider using hardware wallets like Foundation Passport or Coldcard, which keep private keys offline and away from potential hacks or compromises.
Running a Bitcoin Node
Running a Bitcoin node allows users to verify their own transactions and reduces reliance on centralized nodes. Bitcoin Core is a software option that enables users to download their own copy of the blockchain and interact with the Bitcoin network. Alternatively, plug-and-play nodes like Ronin Dojo or RaspiBlitz offer a more user-friendly experience, while DIY options involve building a node using software like Specter Desktop and hardware like a Raspberry Pi.
Using CoinJoin for On-Chain Privacy
CoinJoin is a technique used to enhance on-chain privacy by combining multiple Bitcoin transactions into a single transaction. JoinMarket and Wasabi Wallet are popular CoinJoin implementations. These tools allow users to mix their coins by combining them with other users' coins, making it difficult to trace the original transactions.
UTXO Management for Privacy and Efficiency
Unspent Transaction Outputs (UTXOs) management refers to how individuals spend and consolidate their Bitcoin holdings. By using tools like Coin Control, users can choose which UTXOs to include in a transaction, increasing privacy and reducing the traceability of funds. Efficient UTXO management helps reduce transaction fees and optimize the overall storage of Bitcoin.
The importance of practicing with wallets and understanding backups
One of the common mistakes is not practicing enough with wallets and not understanding the backup process. It is crucial to practice sending, receiving, and backing up bitcoin with small amounts to ensure you are comfortable and confident. This includes testing different wallets, using testnet, and verifying the backup and restore process. By practicing and gaining familiarity, you can mitigate potential panic and mistakes when dealing with larger amounts of bitcoin.
Being cautious about disclosure and publicizing bitcoin ownership
It is advisable to be cautious about disclosing or publicizing bitcoin ownership. Sharing information about owning or holding significant amounts of bitcoin can attract unnecessary attention, potentially making you a target for theft or hacking attempts. It is important to carefully choose who to share this information with and be mindful of the potential risks involved. Keep a low profile to safeguard your privacy and security.
Using app-based two-factor authentication instead of SMS-based
When signing up for an exchange or online service that requires two-factor authentication (2FA), it is recommended to use app-based options instead of SMS-based authentication. SMS-based 2FA has been exploited in the past, leading to account hacks and fund theft. Utilizing app-based 2FA, such as Aegis or Google Authenticator, provides better security. Remember to backup and secure the authentication app to prevent potential loss of access.
Benefits of Multi-Sig for Bitcoin Security
Multi-signature (Multi-Sig) is a security setup where multiple hardware wallets are combined to form a wallet. This reduces trust in any specific hardware wallet manufacturer. With Multi-Sig, backup words are divided into multiple sets, and users need to find the required threshold of backup words to spend their funds. This provides a geographically distributed security setup, where the keys to access the funds can be located in different places and duplicated. Multi-Sig also allows for different combinations of people to hold the keys, making it useful for inheritance situations.
Collaborative Custody as an Alternative to Multi-Sig
Collaborative custody alternatives, such as services like Onjin Capital and Casa, offer a centralized solution where a third-party holds one of the keys in a Multi-Sig setup. This helps in the event of a loss of one of the keys, ensuring that you don't lose access to your funds. However, this introduces a privacy trade-off as the centralized service knows your transactions, balances, and can tie you to your Bitcoin identity. Collaborative custody services provide support and guidance in setting up Multi-Sig, but it's vital to trust and consider the privacy implications of using such services.
