unfortunately, its not even exciting and as far as i can tell, it became far worst than it was just a few months ago.
as soon as you start auto-bet, you start strangely winning and suddenly (out of that pattern) not long after it falls like a rock, no matter how big or small your going for.
if you look carefully the bets/results patterns (no matter the strategy), it becomes quite obvious to a analytical mind what is happening behind the cenes.

i thinking about producing and releasing at some point in the near/mid future a complete/detailed review about the psychology of their business model, how their system works, how they can cheat even using provably fair system, how referral is actually malicious and so on..., also the good points, they pay, yes, they pay, if you have anything to be payed anyways.

for now, if you are not doing this just for fun/rush, i strongly recommend anyone to stay away from multiply.
and based on the general picture i got, i even doubt that lottery works, in other words, if you care, don't waste on them either...
