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.
Wherever any altcoins value bumps up that even bitcoin value bump along with that. In marketplace stocks every digital currency have been increase with together. I noticed some ICO has started few months before that's value seems increased to 100 and more value.
