Still pretty noone uses monero, it gained some popularity as a meme for privacy, but, in the end, just a few people uses it and the volumes are ridicously low. It could have some advantages in darknet situations, like be sure that the retarded stoners dont pay the vendor directly from binance. So the tx graph is obfuscated and theres a privacy gain, but this use has made technologically obsolete by lightning, that works better everyday.
I dont trust noone, in particular samourai guys. I usually verify, and I verified that samourai tools was not so great (the fact that has been so easy to stop them is an hint on how most of the the design of the tools was bad and centralized). They was a joke for expert people that can have a better experience with better tools, and they was flawed in many points so to not make them a good solutions for newbies.
