Basically I had 2.1 BTC for a very long time. Sent .007 a few days ago with no issues, last night I sent .21 btc to another wallet but it never arrived and never was seen by other peers and I can't find the transaction history but the BTC was gone frrom my wallet. Today I reset the blockchain and transaction info to see if it was just a glitch and now I only have .7 in my wallet. Has this ever happened to anyone else and is there a way to see what happened on the blockchain? I am not seeing any other transactions so no one stole my coins but this is very perplexing seeing as how I am now missing what amounts to $1700 USD
