Electrum transfer bitcoin to unknow adress bc1

[Lucius]

thank you @NeuroticFish, I will do that and buy a nano S.

Buying hardware wallets will not give you 100% security, especially if you do not learn how Bitcoin works. Even if you use HW, you should know that you are still at risk of something called clipboard malware and that you should always check the coin address on the hardware wallet screen and compare it with the coin address to which you send your transaction. The other thing is that backup (12 or 24 words) is much more important than HW itself, because anyone who comes into possession of those words can steal everything you own.

I am really a beginner, and i thought I have done something wrong with the adress and the compatibility with coinbase regarding the adress segwit native and others because I don't understand that.

It is very possible that exactly what many have described happened to you, and the forum warned about this danger at the end of 2018.

Electrum vulnerability allows arbitrary messages, phishing

Your Electrum wallet appears to be old or you have deliberately chosen legacy addresses as your withdrawal address was 1Dymcvrnqrt54VrvdihSv4hDt1ZqV7wYLj

Do you use your wallet on multiple devices (same wallet based on same mnemonic seed words)?
Have you setup your wallet before your "stolen" withdrawal on some other device? (I don't mean your subsequent attempts to restore your wallet after your funds have been transfered from 1Dymcvrnqrt54VrvdihSv4hDt1ZqV7wYLj to bc1q4tjunthvhp6c6hqun6yylvy0hewqp4fkgpplde by whoever.)
Have you saved e.g. a photo of your mnemonic seed words on a device which is connected to the internet?

I can't recall that you provided information if the address 1Dymcvrnqrt54VrvdihSv4hDt1ZqV7wYLj is derived from a mnemonic seed wallet. (Though, quite likely.)
If it is and if you stored your mnemonic seed words digitally but unencrypted somewhere, you should consider your whole wallet compromised. (I assume there are no funds left as you wrote that after a wallet restoration there's 0 BTC in it and you're not missing any other funds.)
