I bought 200 ($700 worth) bitcoins in 2012, and I found them last week. Now, my wallet says they are worth $2371959.00 apparently. Is this a scam or do I need to sync my wallet? The computer is pretty old so I'm not sure if it is a virus. Has anyone had this issue?
I'm not sure if you're trolling or not, but 200 bitcoins is currently worth ~2,357,000$. ( Which seems to pretty aligned with the number you are giving.)
There's no virus/scam or bug, the price simply increased. Congratulations.
I'd advise you to make a backup of the private key of the adress you're currently storing the 200 bitcoins on, and either memorize it, or hide it, in case your old PC / ( the harddrive of your old pc) breaks.
Or even better, buy a hardware wallet (such as a trezor or Ledger Nano S) Or a secure new PC/Laptop, and store the bitcoins on there.
