Updating a Bitcoin wallet I have a harddrive with an old wallet but I am not sure what I need to do to see how much BTC I have.

I have read quite a few notes, but I am looking for the latest information. I want to continue leaving my BTC in my private wallet until I decide to move it to an exchange or online.

How do I see how much BTC I have?
To see how much BTC you have, you just need to open your wallet up, make sure it is fully synchronised, and then check your balance. If you don't want to wait for it to synchronise, you can copy and paste your addresses into a block explorer to see the balances on there.
