Hi,
I believe paper wallets are the way to go for long term storage for large quantities of BTC..for me that would be 2
BTC and up especially at the price BTC is valued at now. Cold storage is the key!
I understand what is required and the risks involved with Malware..hackers and keyloggers...so this is what I did.
Bought a new laptop, new printer, usb chip and new camera.
These devices will never be connected to the internet. I downloaded the wallet program and also bought it too via
https://www.bitaddress.org/ Installed both on my new PC and created a paper wallet with the BIP38 encrypt..Printed multiple copies and took pictures which I stored onto the USB chip.
I also tested the wallet to make sure the private and public key match by using the two separate wallet programs. I would not want to place into a paper wallet that somehow send your coins into oblivion or that you cannot retrieve.
So now I have paper and software images of my wallets private and public keys. Since water is one thing to be concerned about I laminated the wallets and also placed it in this plastic mold.
What you see is the Q square of the private key which is encrypted but is water proof. I can literally place in my acquarium! I tested and it can be scanned with no proble,

As far as monitoring your bitcoin public address balance..there are apps out there that do this. And as for hiding your IP address, I use a VPN software where I can show I am coming rom INDIA and thus hide my true ID and not leave any kind of IP original footprint. For instance whenever I goto any forum I make sure I do not use my real IP address. If there are any hackers out there they can see who owns Bitcoins and thus see your real IP. This can give them a possible target. So when it comes to digital cryptocurrency take all precautions. Goodluck!
