Hmmm, you are pretty much arguing semantics. Call it an extended rally or call it a bubble. Same thing. When the price has rallied from $225 to $1350 in 9 months... I call that a bubble. The graph looks similar to when it bubbled in 2013. Sure, it may go a bit higher this time, but the result will be the same.
if it goes from 1300 to 13000 in one month then i'll be fully confident that we're in bubble territory and i'll be running for the exit.
i'd argue that that 200-250 price was the result of a combination of the 2013 peak being partly pure fiction thanks to gox and the subsequent doldrums was price intense suppression from the bullshit exchanges in china. now they're gone the basis of this rise has been far more down to increasing demand. if china was fully functional this price would have been dumped to death before it got anywhere near it.
check the localbitcoins volumes and the constant pressure on block space compared to 2013. of course a bunch of that is down to people trying to get into alts too but this is more than just another nosedive in waiting.
