I believe that 1xbit is trying to do better, I honestly do, they look like they are doing "better". However the problem is that there has been so many problems so far that even if they are doing "better" it is still by far worse than most places.
I guess you think they are trying to do better thanks to their decent behaviour in the forum and resolved scam accusations coupled with the fact that they keep hosting multiple campaigns on a regular basis.
This is all simply part of their elaborate scheme if you think about it. If they are seriously changing, the scam accusations against them would have dropped drastically long ago.
