Can i transfer Bitcoin and Litecoins from Old Wallets PC 2013 to new one on MAC

[Clavulanic]

Dear Neurotic Fish

Thanks for your help...i am not sure what is going on .
I was trying to get Private Key for my Litecoin Address and wanted to move it from my PC LITECOIN WALLET to MAC LITECOIN WALLET but was not successful

When i wanted to get Private Key for my Litecoin Address I was getting the message that Private Key ..................................... is not know (code -4) whatever that means.

When i checked On Blockchain my balance it does say 87 what is correct amount.
I did try to send 2 transactions last week of 0.50 and 0.10 just to see would it work -it did not

Now i am really worried... i have tried to google it but could not find anything to do with this code -4.
Can it be because my Wallet is old? and i received  the message that "Alert Key Compromised, upgrade required"??


I will send you picture PM ..if you have time would be grateful if you can have a look.

Thank you so much..hopefully there is a solution for this

All the best

I am quite inexperienced with Litecoin, but I'll do my best.
First of all, I'd backup wallet.dat and the whole Litecoin folder (it may be in the folder %userdata%)

Part 1. Export.
Make sure the address is correct; I am not sure, but there may be that your wallet "knows" something and the network "knows" something else because of those transactions that were not sent out. Such error could mean that you either try for the wrong address, either you forgot to unlock the wallet first.
Again, I may be wrong; you may have to ask around on https://www.reddit.com/r/litecoin/

Part 2. Upgrade.
It may be a good idea to upgrade Litecoin Qt to the latest version. As you said it's Windows, I expect the installer handle everything and after the upgrade you may even have your wallet.dat in place (if you don't, you'll use the backup).

About that error message... hmm... that worries me.
If you manage to get access to your money, I'd advise you to create a brand new wallet and send your money from the old wallet to the new one, since "key compromised" may mean that your money is not safe.

Yeah that's better idea mate and it should be followed as well so that you can be certain that your wallet is not vurnerable of being attacked by phisers. Creating a brandnew wallet is a recommended thing to do everytime we do have new gadget or other else that hampered your security on different cases. Personally I am also using new waller address everytime I was doing another transactions,  paricularly of another new bounties given like token from a successful ico.

Well..I dont think this bit of Private Keys is "advertised" as much it should be.

I kept QR scans of my addresses but didnt know that i needed Private Keys too..
I even encrypted my Litecoin Wallet with password and luckily i remembered it to unlock it ..Hate to think what would happen if i forgot it.

So,right now i have wallets on PC and MAC too (for both LTC and BTC)..it is like i can have like 100's different wallets with the same Bitcoin for example if i insert the same Private Key ..
Is that right?

Well..i fell like i rescued those coins(apart from those 0.45 BTC i just cant remember sending)..from now on will spend some time learning more about it:-)

Imagine your inputs as banknotes. When you send out money, you will send out the banknote and will get back the change.
Most wallets, internally, create a new address (public + priv key) inside your wallet (wallet.dat or other files, depending on the wallet software)
I think that your 0.45 BTC is in such place. You still have that very same wallet.dat since you did that transaction, right?
Use copy/paste and try again to get the private key for

The address you wrote may have a typo, but I can't find it now on mobile.

You can export your Private key of BTC and import to Blockchain.info or sync wallet core!
I think you must sent with hight fee at the moment for BTC

He can do this easily if holding the private key, yet this is absolutely the wrong time for doing such transactions. They tell to wait for 30 confirmations at least and all transactions are problematic now. It's better to wait 2 more weeks to this tension calm down.
