Be aware that you are downloading software form a website (Electrum) and trusting your money to it. Please check the tarball checksum, at the very least, if you intend to use it.

If you want to be hardcore you can verify the gpg sig. This is how I do it in linux:

Code:

wget https://download.electrum.org/Electrum-1.9.7.tar.gz https://download.electrum.org/Electrum-1.9.7.tar.gz.asc https://github.com/spesmilo/electrum/raw/master/pubkeys/ThomasV.asc
gpg --import ThomasV.asc
gpg --verify Electrum-1.9.7.tar.gz.asc

This should tell you whether the signature is a "good signature" or not.

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.

You are correct. When I looked at Electrum, I saw that the first address was hidden under "used". It was actually there - but hidden.

So - this does mean that I can always send Bitcoin to this address and I will receive it? Everyone can use a static Bitcoin address - there is no need to change Bitcoin address and there will not be trouble, correct?

Thanks for the fast reply, now I will keep on testing and sending Bitcoins!...

You can reuse addresses but it is not recommended. Address reuse makes it easy for anyone to see all your transactions. Remember bitcoin transactions are public information. You can easily see all transactions on a block explorer site like blockchain.info. So it is better to use a new address per transaction. You can generate unlimited addresses so why limit yourself?

Do you mean addresses?

The first address should not disappear. However, you can use other addresses left.
