I invested, i dont know, a month ago, to buy the second gold mine. First payment took a week or a little more to get to me, so dont assume its scam if it hasnt payout for a few days. However. I dont think I'm gonna keep playing, it takes increasingly higher amounts of time to get to the next level of pay, and the way I see it it's not quite worth it. I think a person that played for a few months can expect maybe 10k sat a day, which is good for some and bad for others. In any case the game seems quite popular, according to how many 'spaces' are taken already on the virtual islands of the game. If the data is true, then there are really a lot of players.
