I believe that everyone here like me joined the crypto world for just one main reason. It is to earn extra income and find something to invest with. While we are in an advanced stage of technology, it is a fact that Blockchain Technology really makes it's own way to introduce itself by surprising us with the possibility to earn money. Though on its early stage way back years ago, there are just few who knows the technology when Bitcoin and other cryptocurrency do show its exponential growth in terms of value, then that's the time that many do really have an interest on it even big companies who invested on mining.
