Is there a lightweight client for monero? Like electrum for bitcoin? That does not send private keys to the server like
Edge or
MyMoneroThose in your list are the lightest client that you can get if you do not want to send the Private View Key to the server.
For example: "
Feather" IMO is the Electrum of Monero.
The type of device you are using for the wallet, maybe PC spec makes a contribution too.
It does but it's complicated to give an ETA to OP since he didn't specified his machine/device's specs.
The major contribution to the light client's sync speed is still the staring height anyways.
Even a powerful PC can take hours to sync if it has to start from 10+ years ago.
