Electrum knows my seeds?

[gishab56]

hello

3 months ago, i made a Electrum wallet and let it to make my seeds itself from default option. Should i made another wallet with my words? Is my bitcoin safe?

Is it possible electerum sends seeds to a certain server for the DeveloperS?

No. The way Electrum generates your seed is 100% safe and no one other than you will be able to see it.

You also shouldn't "create a seed" by your own. This is called a "brain wallet" and it can be way dangerous than a normal one generated by the software.

Yep, the seed is safe within Electrum so you don't need to worry about that. Just be sure that you encrypt your wallet with a password so it isn't stored in plaintext on the computer.

For the best level of security, a hardware wallet used with Electrum is your best option. The seed isn't visible to Electrum in this case as it is stored on the hardware device.

Great answer above this post.  BTW -  If you have had an Electrum wallet with unencrypted SEED online for 3 months I would suggest a new wallet.  It might be that your coin count is somewhat low and an adversary could just wait until you place a sizeable coin count on the "ledgers".  Sounds a little "tin foil hat-ish" but I have seen some crap over the years.  I don't like any wallet with keys online (my take on all this), and prefer either a cold wallet two computer approach or a hardware wallet.  BTC is over 3K now!
