Hello,
Suppose I would expand my BTC portfolio to 10 or 15 BTC.....how would you store such a big amount of coins?
Ofcourse I would use a hardware wallet, but if I store them all on 1 wallet and I lose the wallet, or the house gets on fire and it burns, then I have lost those coins forever? Or are there still ways to get to the coins somehow in that case?
Would you advise to store let's say 15 BTC on 3 different hardware wallets (5BTC each), or would you spread it out even more? Ofcourse I'm not gonna buy more than max. 3 hardware wallets but in that case maybe 15 different laptop wallets (Electrum, Jaxx, Exodus etc.) with 1BTC each on it is safer?
I'm looking for the safest way to store a big amount of BTC and to minimize the risks of losing a big amount.
The beauty of Bitcoin is that you store "big" amounts exactly the same way you would with "small" amounts, so practice with a few satoshis:
Make a (cold) paper wallet.
I have written about this countless times, it basically involves a secure computer, it can even be disconnected from internet, using a secure operating system, preferably not installed, booting of optical media or usb thumbdrive, then create a wallet, which for speed purposes i tend to recommend the spv one, write down by hand a dozen words in a piece of paper that you have to keep very safe and away from anyone seeing or harming, preferably make (also manually) a second copy, and print your wallet addresses. After you finish this process you turn off the computer and end with a paper wallet that nobody can ever hack, unless they get hold of the 12 words.
Technically i would advise booting the Linux Distro
TailsOS, and there use Electrum, to create the wallet.
You will rarely ever touch this wallet again, but when you do want to move funds from this wallet, you repeat the process like when you created the wallet, boot pc, open Electrum, but instead of create you will restore a wallet, using those words you kept real safe, do your business and shutdown.
The shutdown is important, because unless you haven't noticed, everything you did goes poof, except the existence of that wallet (priv keys) in the Bitcoin network.
You can play with hardware gadgets if you want, but they are not worth unless you are constantly using it to move funds. You could have such a device for smaller amounts and keep the big sum in the cold wallet, and always follow this protocol when handling it.
With Bitcoin, you are your own bank. Take it seriously, no excuses. Transactions are final, remember that.
If you are familiar with different OSes and wallets, be my guest. Technically you could use something like OpenBSD and the true Bitcoin core wallet running a node as well. Just please, for the love of God, stay away from Windows, OsX, Android and the like for the purpose of creating cold wallets intended to store important sums.
Yes, its intentional, don't use your favorite games and pleasure OS for serious business. 10+
BTC is serious and we have countless people coming to this forum crying over lost funds my making simple mistakes, thinking somebody can help them when its too late...
