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.
You have only 10 to 15 btc and there are people who are storing 100 btc on a single wallet. You do not need to make things complicated. More the wallets, more the private keys and it will make every thing confusing. Just keep a single hardware wallet and keep the private keys in two different places and that will be enough.
