this case na old format for people wey sabi, but person wey no too dey enlightened go still fall for the trap. some people go somehow sense danger but dem no get enough conviction to see say na danger until dem fall for am. wetting dey make people fall for most of this scam na because of greediness of trying to become rich overnight. but the best and easy way to know say na scam na when you don notice say the offer too dey real to be truth. when person tell you say invest #1m to get #2m within 24hrs sopos tell the person say na scam be this, because you go ask yourself say which business go fit generate such profit. that mean say the profit don pass 3x na because before dem give you 2m that mean say dem don collect their profit. so this na things people sopos reason when offer like this come to you. if you do this calculation, no fit fall for them except you are destined for doom or failure.
 
that one na good idea but i doubt if people go fit get the time to keep updating that king thing for here every time. most of us don get alot of experience so hardly we fall for that kind scam. but the thing be say as update dey cast, naso new one dey surface so we need to dey careful by all means because some scam go look pure until you fall for am.
