<p>There are no methods available to other people (third parties).

Perhaps some old "wallet.dat" files on a PC that indicate you had a desktop wallet with control of your own private keys. Maybe an app on an old phone in a drawer. Perhaps a written down recovery seed or private key in a locked box you use for important documents.</p>

<p>In order to get access to the bitcoins, you need to have the access to the bitcoin address or the bitcoin wallet (usually a <code>wallet.dat</code> file) containing that address.</p>

<p>If you have the address, you can check if it has any balance on it with various explorers. <a href="https://www.blockchain.com/explorer" rel="nofollow noreferrer">[1]</a> <a href="https://btc.com/" rel="nofollow noreferrer">[2]</a> <a href="https://live.blockcypher.com/btc/" rel="nofollow noreferrer">[3]</a></p>

<p>You can access the address if you have its <code>private key</code> (password).
If you have the wallet.dat file, you will need a password to unlock it if it has been encrypted. Else, you can access it without a password.</p>

<p>I recall accepting bitcoin payment several years ago when the concept was fairly new. My trouble is, I don’t know what happened to the bitcoin after the receipt. What methods are available to search for “lost or abandoned “ bitcoin?
Thanks in advance

If you do not control the private keys to the addresses where you received your bitcoins, there is no way to recover it. However, if you were using a third party service that were holding your bitcoins for you, you can enquire with their customer service department

In order to get access to the bitcoins, you need to have the access to the bitcoin address or the bitcoin wallet (usually a `wallet.dat` file) containing that address.

If you have the address, you can check if it has any balance on it with various explorers. [[1]](https://www.blockchain.com/explorer) [[2]](https://btc.com/) [[3]](https://live.blockcypher.com/btc/)

You can access the address if you have its `private key` (password).
If you have the wallet.dat file, you will need a password to unlock it if it has been encrypted. Else, you can access it without a password.
