Monero is the best privacy coin there is, bar none. It has privacy at top level for all transactions unlike others that pick when they want to use it. The way monero works is superior and all transactions will get hidden easier the more people use it.
Seriously?
Monero is security by obscurity. You have to trust them that "is secure".
This is BAD from the security point of view.
All (honest) security professionals trust only open source software. And monero is not open source.
