Do any Bitcoin dice gambling sites still do the milestone promos? I think Bitsler was the last one to do it and the rest stopped.
They were many issues with these milestone promos. Usually what happens is a massive amount of bots starts to bet during the timeframe that the milestone bet is passed and usually its some newbie that wins the price instead of some regular gambler, so it doesn't really benefit the site.
That's why most sites instead of doing milestone bets they just do promos instead.
Basically its similiar to what happened with faucets. They were fine for years until the abuse started and most dice sites had to remove them.
If I not mistaken, cryptogames still do this though but of course it is not as fast as bitsler but there is something like primedice can do and other site can't. There is still positive and negative thing on each site provide, it depends on the players as well which suits them better. And why does newbie win becomes such a bad things to the owner? Anyone win will nothing to do with them because they already set some budget for the prize so anyone will going to win one of the prize
