I've never really checked privacy coins, i only know that the "king" of them is Monero (XMR), but there are so many new privacy focused coins out there that's impossible keeping track of them.
I'm a fan of privacy coins but in the end we Buy and sell things still mostly in FIAT, so i only see speculation arount it
i think that this can be a good idea and you are not alone who likes this kind of things atvteh ryptocurrency world
