## Introduction
Status should follow all standards as possible. Whenever a feature is needed, it should be first checked if there is a standard for that, if not, Status should propose a standard.

Sourcecode: https://github.com/status-im/status-react/blob/develop/src/status_im/constants.cljs#L240
Observation: BIP44 don't solve privacy issues regarding the transparency of transactions, therefore directly connected addresses through a transactions can be identifiable by a "network reconnaissance attack" over transaction history, this attack together with leakage of information from centralized services, such as exchanges, would be fatal against the whole privacy of users, regardless of BIP44.
