Seems right, they have a lot of update and added some new feature on the wolf.bet last September 19, 2019
After 2 days of that new features and update added, the signature campaign has started to look some participants.
For sure they just waited this as what @Zwei said on last day of the first roud sig. campaign and they did this another new round of campaign. Very good job, wolf.bet team!
They have also enabled the Russian language support (with a little help from me)
All I can say is that signature ads work. I haven't gambled for 2 or 3 years, came back to the forum to buy some AWS codes, saw the wolfbet signatures and ended up losing a few hundred doges LOL
The betting speed in the Autobet mode is fantastic
I have yet to see a casino that would come close to such speeds. The best that I have seen is like 1 roll per second (though I don't know how fast you can bet via API). At wolf.bet I can get more like 3 bets a second, though it slows down a little after a few hours of continual betting. I'm running a martingale setup in a separate instance of Chrome but I still have to restart it now and then. Hope this will be fixed soon
