The interesting thing about this bull run is:

If this time things really are different and this rise is due to major money coming in ahead of the wealth/hedge funds, then the parabolic rise in the charts would be indistinguishable from a bubble. Because of so few coins available and the really thin float on all the exchanges. Especially if the CME Group futures trading comes online by the end of the year, and one or two Bitcoin ETFs pop up next year, then this may not come back down like people think.

A bubble that never really comes back down to previous levels isn't a bubble, it's just bullish interest. Like what can be seen in the charts of Tesla, Netflix, etc.
