I don’t know anyone personally who’s also into forex trading. 
I don’t know if i’m “rich” but I am doing alright.
I’ve been trading forex full time for years. 
Till now i do not know any trader who became extra ordinary rich within my circle. However I find many traders who are doing forex successfully to support their financial needs. All traders can not get same success only few can be rich . I think if you are getting regular profit over the amount invested in forex market you need not to run for richness.
i can’t say if the people i know are rich by forex trading, but we are making a livelihood out of it. so kind of a win situation for us.
