You need to invest a lot of time, money and effort in order to get money worth mentioning out of Neobux. To add insult to injury there are hints that Neobux is actively using its members browser to attack competitors sites.
If you want to make some money on the side without having to invest hours infront f the computer I would recommend clixsense ( I will shamelessly post my referral link since it is also in my interest that you make money).
Even though clixsense hass a high minimum payout of 8$ you can earn 2-3$ on an average day in about 1-2 hours. If you are lucky and you are inhabiting 1st tier countries like the USA, Germany, GB, etc you mak 5-6$ on average just by completing the daily list.
So tl; dr: If you want to make some decent money with negligible effort you should NOT try Neobux --> chances are that you will lose your money instead. Instead I recommend Clixsense: http://www.clixsense.com/?*******
