I'm new to cryptocurrency and I start studying this couple month back. Through out, I'm having a annoying 3 question regarding wallets. Appreciate if someone could help me to clarify this.
1. Why does the wallet public address keep changing time to time ?
2. No matter even if it changed, you can use older addresses, then what is purpose of designing them to change time to time ?
3. For how longer can an old public address use after changed to a new address ?
thats a good question made by a newbie,
1-2. every time you use your wallet its usually keep changing for more security purposes, remember bitcoin transaction is anonymous, there are more bitcoin wallets that not have self generated public wallet address so everyone can track how many bitcoin the owners have, so you are lucky to choose a wallet that have self generated public wallet address for more anonymity.
3.you can use it when ever you want, that generated public addresses can be use as long as you want it or not, you can also delete that addresses if you want and change to the another one you like.
