In my opinion, we are still in the beginning of Bitcoin. Less than 10 years old is nothing. So I would place Bitcoin in the awareness stage to compare with your graph. There are still a lot to do, a lot to see
Indeed, although we are in the early days of bitcoin, however, the strong outburst of altcoin in the bitcoin platform has made all of us trapped in a bubble, and if it continues to grow, It can break at any time.
Yep... the alt coin and ICO token market was definitely bubbly, although it seems to have calmed down a bit. To me it actually looks like most alt coins are in the early blow off phase of the current cycle, with a couple of coins and tokens lagging behind. Of course it might just be an alt coin bear trap, but I think that alts already have grown way beyond what is healthy and will largely depend on Bitcoin's next movements.
