All i can say if all holders do massive selling will affect the price and it will gonna die if investors are in panic selling And if the wallet provider is being hack or bankrupt it may also 1 factors that bitcoin might dead.
if price goes low
the bulls show their support
if price goes high the bears show resistence
that is how trading works, BTC is where it is now due to demand vs supply
and according to VPRO some miners are/were running at a loss (oct 2015) when btc was below $300
which would indicate the price to be undervalued at that time.
Right now that seems to have adjusted and BTC is trading where it should be.
even if big whales dump a shitload, there will always be other whales looking to pounce on that oppurtunity and buy a shitload at low prices,
as would probably many non traders, the low price would attract attention and create demand driving price back up (fast slow whatever)
as for companies going bankrupt, they go bankrupt do to fiat, and more importantly most likely due to the interest fees they must pay to their fiat creditor.
hacking, is just poor business model, by any company that wants to work with BTC but thinks security of its servers is not priority.
this gives more claim as to why we need P2P, as third parties cannot be trusted when they put (fiat) profits before prople.
