From my point of view i would suggest only one forum that i know is bitcoin garden its is similar to like this but its interface is very very good from this forum and it also same as this forum they also provide signature campaigns probably and it can be the mordern interface of this forum and you can join it and whatever you do here you can it there also.
Yes I have heard about the bitcoin other forum because the bitcoin is increasing more and more so buying the bitcoin will help the people to buy and this is the best forum more than the other bitcoin forum so I hope the bitcoin value will increase more and more, this forum has a lot of the information and it is getting wide day by day, as I can see the bitcoin will increase the value of the forum as the bitcoin talk forum is the best forum.
