To clarify, what do you see as the current issue for SPV scaling? Light clients seem to scale very well in practice.

@chytrik Apart from the initial sync, I think it is quite slow for the majority of the time when starting up up on the phone, my opinion may be biased as I have only used Bread Wallet's and Loaf's SPV Wallets. From my understanding, Bread only generates k child keys, so with a full HD wallet on mobile, it would be hard to scale at say 200+ addresses, no?

Electrum has the ability to [communicate entirely via Tor](https://bitcoin.stackexchange.com/questions/74499/how-can-i-use-bitcoin-privately-with-the-electrum-wallet-and-tor), so the server will not know your IP address.
