Re: Send BTC to this wallet 14V6pKw3AaPcyRpqvff26B2eLdiNRJSz8b: small reward
So, you're asking for "just" 0.08 BTC. At current preev rate, you're begging for a measily $650, just to identify an account that cannot be identified by this method... But you give your word you'll return the $650 
I think what he is saying is that he senT bitcoin to that address, but his English is difficult to parse completely. And then is asking for help to figure out what web site it belongs to.
Hmmm... Indeed, after reading your reply, i can conclude i might have misinterpreted the OP.
I apologise to the OP.
His problem seems pretty hard tough... The address looks like it's part of a very large wallet... The op can try out services like https://www.walletexplorer.com/address/14V6pKw3AaPcyRpqvff26B2eLdiNRJSz8b in order to identify the wallet...
Following the above link, we can conclude following addresses are part of the receiving wallet: https://www.walletexplorer.com/wallet/0000fe51ae40e7cb/addresses
If you manage to identify one of these 237.000 addresses, you'll find the owner of the wallet... You can use google, or the searchfunction of this forum... with so many addresses, there is a big chance of finding a match.
Good luck OP!
