Thx , but why use bitcoin core in desktop because fee or they are the same in web wallet
If you use a desktop wallet you are in full control of your private keys. This way you dont have to rely on some service to keep your coins safe. This is just my view, there is no best wallet for everyone. For some an online service that keeps your keys safe is a better choice. Thats why there are so many different wallets, because someone in the past was not happy with the ones available and made a new one.
