Biggest Traffic, indeed, I search your site alexa data.
Global Rank 22,927
India Rank 9,054
Your site is quite popular, maybe the second largest bitcoin dice site after primedice now. Primedice's rank is 48,360, you are over them.
Yeah, I think it's because Baryom is very very active in marketing strategies with the site,. Primedice now is like a sustaining machine already with it's traffic maintained everyday, continuing this Bitsler will be the next big thing in dice, but still Primedice will be the legacy.
Indeed, this goes to the marketing team of Bitsler. Their signature campaign is running for quite some time now and that must have helped the site get more attention from the community. I also agree with you in stating that Baryom also made this possible because he is very active in his thread and usually answered all the questions personally which are posted here. I'm also thinking that their fast dice setup (don't know what its called) attracted many gamblers and I must say, it is a very neat feature.
