I created 4 wallets in Electrum.
Now I am sending the money from the market maker to my own wallets to be more secure.
I have written down the seeds, addresses and will store in a vault.
For backup, you only need to write down the seeds (12 words).
All the private keys, public keys and addresses can be restored with just the seeds.
Of course, if you want to send bitcoin to your wallets, you can write down your addresses as well.
However..... I started to send some Bitcoins to my wallets and...... After some Bitcoins all the addresses seem to change in the wallet. Am I doing something wrong? I have sent 1 Bitcoin so far. I sent back and forth. But the receiving addressses in the Electrum Wallet changed and the first receiving address no longer appear.
Can I securely keep on sending the first receiving address Bitcoins - or will it go into the dark hole of something?
I noted the first address of the wallets and send all of the wallets to these first addresses - but addresses seem to change.
Now - what to do? I will send some more 18 Bitcoins and can not risk. What do you advise me to do?
I printed down the first addresses of the initial status of all the wallets - can I send to first address of them although they no longer appear?
Abdussamad is right.
You can use the same address again and again, and will not pose any security issue.
But, once you spend the bitcoin on an address, I would suggest you to not use that address again, as the public key (not to be confused with private key) will be known to the world.
