It's a digital currency that has demand, everything with demand will get valuable especially when the supply is limited. But where does the demand come from? Is it popular simply because of speculation and media attention? If so, I can understand that most shares work in basically the same way the difference being that the investment there is also based on the assumption that you will make money. you just need to understand the strategy of crypto market and its up and down for this purpose, a crypto trading bot would be a suitable fit.
