Personally I use this app. Its gave you Satoshi for watching ads. Its totally fake and it is a scam. Bit coins never built with watching ads. They show you are really earning Satoshi. In this app too much apps are showned. Actuall Satoshi is built to solve the problem. Nice hash site is a good site to built Satoshi in which you Actually know how bit coins mining works. And if someone really want to mine bit coins they use nice hash site and sell their cpu Power to earn Satoshi. No one app or site give you Satoshi for watching ads this type of sites and app are totally fake
