The must-haves for every bitter Bitcoin investor can be listed as follows: A cryptocurrency exchange account, personal identification documents for using a Know Your Customer platform, a secure Internet connection, and a payment method. It is also recommended to have your own personal wallet as well as a clearing account. Valid payment methods using this method include bank accounts, debit and credit cards. It is also possible to buy Bitcoin from private Bitcoin ATMs and P2P exchanges. However, keep in mind that Bitcoin ATMs have increasingly started processing on presentation of government-issued IDs from early 2020. Privacy and security are important issues for Bitcoin investors. Bitcoin is physically unavailable and telling about large stocks proudly is often a bad idea. Anyone who receives a public address private key in the Bitcoin blockchain can access and transact. While it's clear that the private key should be kept secret, criminals may try to steal your private key if they find out that you have a large amount of assets. Note that everyone can see the balance of the public address you use. One solution might be to keep significant investments at public addresses that are not directly linked to smaller amounts used for transactions. Anyone can see the history of transactions made on the Blockchain. However, while transactions are publicly recorded on the blockchain, identification of user information is not recorded. Only one user's public key appears next to a transaction on the Bitcoin blockchain. In a sense; Bitcoin transactions become more transparent and traceable than cash but on this occasion, Bitcoin can be used anonymously. International researchers and the FBI claim that they can trace transactions made on the Bitcoin blockchain to other online accounts of users, including their digital wallets. For example, if someone creates an account on Coinbase, they must verify their identity. Now, when that person buys Bitcoin; this purchase will depend on the person's name. Even if he sends Bitcoin to another wallet, it can be traced back to the Coinbase purchase linked to the identity of the account holder. However, this shouldn't worry most investors because Bitcoin is legal in the US and many other developed countries.
