Are there still people who really use the Currency exchange board to buy or sell Bitcoin for fiat?
Yes I am one of them. Probably do a trade every few months.
There are several high trusted, long term, members that use it.
There are also several members who unless you spend a lot of time there you will never know about because they spend 90%+ of their time trading.
They have decent trust and are here to do what they do. Yeah, you have to search a bit for them and read into their feedback a bit but they exist.
