Why I have some many address when I only created two wallet address in Electrum? I am new to this. I have created two new wallet addresses (labeled init and init2). However, when I click &quot;View &gt; Show Addresses,&quot; I found a lot of addresses.
Why?
What do receiving and change mean on the Type column?
Can somebody help?
Electrum will generate a certain number of addresses in advance. It doesn't really matter since it will always generate the same addresses in the same order thanks to using Hierarchical Deterministic (HD) wallet, but you can modify the number of addresses generated if you want, it's called the gap I think.
The gap can sometimes matter though if you're using some software like Electrum Personal Server or BTCPay, if you received a payment on an address that is outside of your gap (for example, Electrum only generates 20 addresses and you've got a payment on the 34th), Electrum won't see this payment and it can make you believe it's not there. If it ever happens, relax and augment the gap until you find all your payments.
receiving are the addresses you will use to receive payments, change addresses are automatically used by the wallet when you spend bitcoins to send your change to. In theory nothing prevents you to directly send bitcoins to your change address (I mean those addresses have nothing special from a protocol point of view), but it's pointless and bad practice don't do that.
