If you're looking at the proce as the only indicator, then see, we are at $5200 with hardly 2% of the world population. Think what will happen when the adoption goes up to 10%. Think about the amount of demand we will have. That increase to $19k was inorganic and everyone knew it wont stand. Look long term, leaving the spikes of 2017, we are pretty much going up. Btc definitely have future even if you're considering only price point of view.
