I just noticed that I send the bitcoin to the same address as I received it from. I'm not learned, but if I send bitcoin to a send wallet then they are lost?

Thank you.

I got the bitcoin from localbitcoins.com

I sendt them to the seller there?

Hi

Yesterday I tried to transfer some bitcoin to Bitfinex. After looking for 30 minutes where to send the money, I found the three wallets there.
Then I copy pasted the address from the Bitfinex account into my pc wallet and sent it. But it never came through. Then I noticed that the funding wallet address in my Bitfinex account doesn't match the address in the transaction log which is very strange because the Bitfinex wallet address is the only address I saw (looking a long time for an address to send to, not copypasted from other sites).

1D38xn57NgSpGKxuz1mJwdvdCuq4QgGnHa  - is the address I tried to send to, the funding wallet in Bitfinex,

1MihufoBpGHS1B3FPhVi62rCMwKPzZAuqU   - this is where I happened to send them. I haven't seen that address before. Seems this address got my bitcoin from 1HjCQ6us9xpT5YRzCBqxkBJPAjfn9s8weL which I haven't seen either, my wallet I send from is 1L5mZLJt17bn5Z2V6EERtZ5PrhUajkiUy4.

This is the transaction ID 7b502cbf4f914439d3edaf4f78ac37061a0c5773159dcbab7c680ec190b8a441

Can anyone tell what happened? or are they lost? I've sent a support ticket to Bitfinex but I don't really know how to explain it 

Thank you
