Yeah right what you say, I myself feel increased knowledge after joining crypto currencies. I became more knowledgeable about technology. I am increasingly aware that the presence of this technology has a positive purpose to help our work. We become easier, faster, and cheaper. I myself became motivated to be able to participate in creating the same technology. Therefore I always invite people around me especially those who are young to join and get to know crypto currencies deeper. No one knows, maybe this crypto currency in the future will have a bright future and become a more powerful technology.
