As the saying goes dont keep your eggs in the same basket. So have you saved all of your btc in mutiple wallets\software?
This term is usually used for altcoins that we should not put all the money in a single altcoin, but rather divide our portfolio in different altcoins.
Usually, people do not think to keep single crypto like bitcoin in multiple wallets. People usually have one wallet containing all their bitcoins and those who have a large quantity of bitcoin have only one hardware wallet to store the bitcoins.
Since the bitcoin is valuable and its price is increasing, we should consider dividing our bitcoins in different wallets. So in case, a private key of one wallet is compromised, we do not lose all our money. Let's suppose you have one bitcoin. Better two put 0.5 BTC in one wallet and 0.5 BTC in another wallet to be on the safe side.
