I personally think it is just scam because if everyone can make $400 per week then no body gets poor this is what i have found:
I am using this site but not sure it is a scam or not as from my experience it looks like a scam because the withdrawal amount is really high it is 0.049 so it will take a long time to make it. so I decided to ask here so can save my time instead of clicking after every few hours in a day Edit: With the input of many users I think it is clear that it is a scam because most ppl confermed it that higher you will go the lower the btc reward will be and also most boxes will be empty. And if they are paying sites why don't they lower the withdrawal amount to 0.001 as anyone with lvl1 can achieve it with opening just a few boxes. THE SITE IS A SCAM AND DONT WASTE YOUR TIME ON SUCH SITE THAT YOU WILL REGRET IT IN LATER ON
