Monero is just a tool no need to be upset.
It's picking up in an area Bitcoin is lacking in.
It wouldn't even exist if privacy wasn't always an afterthought. With respect - I've been reading your brother and you say it's just a matter of time for years...perpetually just around the corner.
It's hard to be angry with those who get tired of waiting and finally say "fuck this" and just build out and start using those privacy tools
