Seems they stopped advertising their site so the source of invest is low now!  it's about one week stuck in level 8! i think the problem is the lack of manual cash-out! they need to fix it asap! just having auto cash out is not a good idea!
so early to end! with a good advertisement they could have reach level 10-15, like makebtc, at this time it has much more rewards for (leveling up gives like 25%) than makebtc at level 15!
 so 4-5 more level you could reach your main actual invest then you could grab just reward! but in in makebtc  you need to get at least 10 level up to reach some reward!
Update: this is scam! they never pay!
