First of all I'd like to thank all those people here helping people out in their time of need. I really appreciate it 

But lets get to the point: I tried to send (3. January 2018) 0,03 BTC to coinbase from my old multibit (version 0.5.15) wallet. My transfer fee was a bit low 0,0001BTC (44 sat/B). Last night I registered to antpool and used their accelerator successfully but in the end it seems like it didn't do any good.

Why does it show that transaction amount is 0,044 btc? It's like there is a two transfers and 0,014 part is addressed to my wallet. Is it possible that there is some transfer from 2014 that I didn't receive back then? I used to mine in 2013/2014 and my wallet is from that time. I'm also worried to upgrade my wallet before that transfer is concluded. One thing that I noticed is that blockcypher shows confidence of 80+% and it was 33% earlier. Does that tell something about that transfer?
