LoyceV - yes one of the addresses does end in an E - is that a bad thing?
I'm just an old fart so Tech takes me a bit to get my head around but I'm always learning.
If you want to make a deposit I'll give you another address just in case I can't access that one anymore?? 

Royse777 - if BTC tanks that much mine will be well and truly sold beforehand.
I think it's more a principle that anything - yes the exchanges do have their terms and conditions and they make sure they tell you that if you make a mistake your coins can be gone forever.
I deposited my funds to their exchange, I purchased BTC and paid a fee to do so, they clipped me on the USD rate and when I tried to transfer my BTC to another wallet they screwed up the transaction.
The same should apply to them. If they find their error and chase me for the funds then I will return the $342 from the original transaction that they stuffed up.
I doubt they will try to get the regulators involved.

Yes, this is just a forum but I appreciate the input from you blokes in explaining the processes to me - Thanks a lot!!

Just to clarify.....if at some point in the future they persue the transaction then I will return the $342 for the original transaction that they screwed up - cash not BTC.
Tough one - if I screw up a transaction then my BTC are lost forever. Exchanges have plenty of disclaimers explaining this - does it work both ways?
If you have my bitcoin address please make a deposit to confirm  

Thanks for the informed feedback and help to explain.
Transactions both happened and confirmed - 0.03290264 BTC x 2 in my hardware wallet.
Not very often the small guy gets a win from the big end of town.
I think I'll cancel my account with the exchange and see what happens.
This could be the gift that keeps on giving as the BTC price increases

 
   















   


 
   















   

Looks like I might have scored a Christmas present???
Both transactions confirmed on my Ledger.
How do I show screenshots on here?
(prefer not to mention the exchange)

G'day, I'm an old fart who's been collecting bitcoin since early 2017. I've got a rough idea how it all works but I still freak out when I have to do transactions so I would appreciate some advice on a strange situation.
Back in September I did a small sample transaction from an exchange to my Ledger Nano S - worked perfectly so I went ahead to transfer the full exchange BTC balance to the Ledger as well.
The transaction status came back cancelled so I just left the balance in the exchange because I couldn't work out what happened?
Today I decided to do the transaction again and this time it worked with no problems.
When I went into the Ledger to make sure it was received I noticed that the exact same amount was also there for the previous transaction..... so it went through twice.
To me it seems like the exchange screwed up somehow but how can that be given the foolproof nature of the blockchain??
Can anybody set me straight on how this shit happens?
