Coinchat is basically dead, they've changed their name, and they no longer give out bitcoin. Would probably be good to remove them from the list.
but I have email from admin of this coinchat that after changing management they are active again and doing same work lets join us again but I never check but they are working with this name https://loquacious.cc/
but I not agree with this that you buy premium membership and then they ban you I am working with them for last 6 months and have never issue its just happen when you do something wrong its very fair and good site
