If I am not wrong there was a similar promotion on the partner site sportsbet.io earlier and from what memories I have of it, it was a huge success at that time. I wish the same for bitcasino.
I think you're referring to the live casino promo because afaik the promo on their telegram channel isn't the same on sportsbet or at least I haven't seen any promo where they'll also give out 3mbtc rewards to several users.
Things in Bitcasino.io are going in an impressive way, 1BTC, the bets for only 5mBTC a day, WOW I think Bitcasino this time is kicking it from Home Run, it is a super promotion, besides those surprise boxes are very juicy, the truth is this is one of the casinos that causes the most excitement in its players, the fact of 1BTC makes anyone's eyes shine. And the best thing is that it is until the last day of this year! For one to be able to participate and have the option to win 1BTC in any game it is very difficult, because what is at stake normally must be very high stakes, but if we take into account that it is 5mBTC daily and every day it is actually a great opportunity.
In this promo it's unlikely for anyone to win the entire 1btc but it's still worth getting a piece of the pie at the end since a lot of people will drop every week.
Can't say much more. Just stay tuned
