Before we decide that sharing bitcoin address is compromised or safe, we must understand few important aspects of bitcoin address and its security because this information guides you in deciding whether to share the bitcoin address to anyone or on any website. Bitcoin is the most privileged cryptocoin in the current crypto world. Any bitcoin user can generate bitcoin address without even having an internet connection, and additionally, it is not necessary to register with the bitcoin world network. Thus people can create such address with the help of the software available freely on numerous websites. Technically, a Bitcoin address is a 160-bit hash of the public portion of a public/private ECDSA key pair. Using public-key cryptography, you can “sign” data with your secret private key, and anyone who knows your public key can verify your signature legitimacy.
A bitcoin address includes 26-35 alphanumeric characters with similar to 1, 3 bc1 which is a digital designation. A bitcoin payment address looks like bc1par0srtr5xfkny3l613lydnw9re59gtzzkf8ndq
However, this is one of a kind of bitcoin address format, and in fact, there are 3 other formats of such addresses. Those formats are P2PKH, P2SH, and Bech32. You can think of the address of your bank account number where the money can be received or deposited by yourself or third parties. Generally, most of the bitcoin address consists of 32 characters with random uppercase, lowercase, and numbers except “I” and “O”. These two letters have never been used till today to avoid the ambiguity. Bitcoin addresses are a consequence of generating a public and key pair. The address is known secretly to wallet owner. Therefore, this is entirely safe and secure if your storing device is not compromised.
Without sharing your bitcoin address, it is not possible to receive funds from another party, so you have to share the Bitcoin address without a second option. Now the question arises that what can happen to my address once you make it public. Hackers can manage to find your address, but cannot do anything until you share them your private keys. The private key can be understood like the password for your bank account for transaction requirement, thus without revealing your private key, people can locate your address, but cannot peep into your account details or be able to do any transaction.
These addresses are not crypto wallet nor balance accounts. You can use it to receive the crypto funds. These addresses are just like bank account numbers where other parties can see and deposit, but they cannot withdraw or send money from that account. Only the owner of the address has the power to send money if he/she has other private keys. Bitcoin address has a built-in check code, so no one can send the bitcoin to wrong address. If the address is valid, but without an owner in such cases the coins sent mistakenly are lost forever and cannot be reverted.
To conclude, it is very safe to share the bitcoin address to another by keeping the private key within your limitation. The private key cannot be accessible to any other third parties on any aspect.
