  Yes, the capitalization of letters in a Bitcoin Core address does matter. Bitcoin addresses are case-sensitive, which means that a lowercase letter and an uppercase letter are considered different characters. Therefore, if you enter an address with incorrect capitalization, the transaction may fail or the funds may be sent to the wrong address.

  Absolutely! Bitcoin Core addresses are case-sensitive. This means that '1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa' and '1a1zp1ep5qgefi2dmptftl5slmv7divfna' are two completely different addresses. It's crucial to double-check the capitalization when sending or receiving Bitcoin to avoid any potential loss of funds.

  Yes, Bitcoin Core addresses are indeed case-sensitive. This is because the address is a cryptographic hash of the public key, and even a slight change in the input will result in a completely different hash. Therefore, it's important to pay attention to the exact capitalization of the address to ensure the accuracy of your transactions.
