Hi, Hardware wallet is expensive to me. You talked about electrum destop wallet but I don't know much about it. could you please let me know how safe is it? how it works?? The price? Thanks.
Electrum (as any other desktop wallet) is as safe as your computer is.
If you are browsing shady sites, downloading cracked software or running a cracked OS, chances are VERY high that your computer is infected.
Any (non-hardware) wallet would be not safe on your PC then.
However, if you have everything up-to-date, a good AV and use lot of common sense, your PC is probably clean and relatively(!) safe.
Electrum is free. And this is the ONLY official site to download it from:
https://electrum.org/#home.
Make sure to verify the signature (or AT LEAST verify the hashsum of the file) to make sure you have downloaded the original version. There are quite a lot guides on the internet about verifying electrum downloads.
The process heavily depends on the OS you are using.
