Edit: Looks like the error was with my wallet. When I contacted support, they said to have the wallet rescan the block chain. After doing that, my balance went back to 0.
I'm new to bitcoin, but something happened recently that confused me.
It seems one of two things has happened:
A. I received the same payment twice from coinbase. B. I managed to completely forget a payment made into my wallet from another source.
Possibility A seems very unlikely... but I did receive a payment in my wallet on the 16th that BlockCypher says occurred on the 11th. (I can show the screenshot if anyone cares.)
Here is the rundown of all the transactions (in order) I know of.
I bought 0.02 bitcoin at coinbase.
On Nov 11 I sent 0.01 bitcoins to my desktop wallet. Transaction here.
On Nov 18 at 13:05 I sent most of that 0.01 to nice hash. Transaction here. (This seems strange to me now... I sent 0.00948.... I would have thought I would have just sent the full 0.01 I got from coinbase.)
Then I decided I would send some more to nice hash, so I withdrew the rest from my coinbase account. Transaction here.
After receiving it in my wallet, I sent everything in my wallet to nicehash. Transaction here. The version of the transaction at nicehash (receiving) is here.
So at this point I had (minus miner fees and such) sent 0.02 btc from coinbase to my wallet and then from my wallet to nice hash.
Then, right after I sent this money to Nice Hash, I see a receiving transaction in my wallet, but it is the original transaction from Coin base... the money I thought I had already sent to nice hash 6 days earlier.
So (as far as I can recall), I only paid for 0.02 bitcoin, and yet I have 0.01 bitcoin in my wallet and I have deposits into Nice Hash for 0.02.
I'm hoping someone who knows how to read the blockchain can indicate where the extra 0.01 came from. Unfortunately, my wallet only shows the two transactions from the 18th.
