Yesterday comparasion of cryptos with smartphones came to my mind... Smartphones was technology that was going only upwards parabolic basically until now. Because world needed it and was ready for it, so during few years parabolic, and I dont think that anyone can say that it was (is) bubble. What if cryptos are the same and we will go kind of only upwards (of course with some corrections, but kind of only up) because the world is ready?... Just an idea, I dont know :)
