one last question that is a bit different. the only way to have one private key/public key pair for a particular wallet is to only have a single receive address, correct? i plan to set up a temporary wallet and then a hodl wallet for long term saving. for the hodl wallet, only having one address and one public/private key pair would be ok and simpler to keep track of if my short and medium term plan is to only fill the wallet and not spend, yes?
Will the funds be coming from a single source?
If yes, then I think it's fine to use a single address for the "
hodl wallet", eg. ExchangeA -> hodl wallet's address;
but not if it's coming from multiple sources like your "
temporary wallet" and exhanges, because you'll end up linking those sources to each other and to your hodl wallet.
how often is it recommended to make a new back up copy of the wallet.dat file?
If says "
HD" at the lower-right (
doesn't have slash), your backup is enough to restore the newly derived addresses.
But if you want to keep the labels updated, update your backup as well.
