Privacy pools only “work” if they are federated because laws throughout the world are not uniform, but being part of the “wrong” federation can make you unlawful. In the end, fear will prevent people from joining, and that fear will spread to the pool developers since at least one federation will do something another country does not like. I’ll fail before it gets started. Just use Monero.
There is no Monero company so if you want it popularized you need to be part of the solution. Go to or start a user’s group. Take part in localmonero.co. Convince people to use monero for remittances and get stores, especially gold and silver shops and pawn shops to accept or sell monero. Etc
