Bitcoin's future prospects could be better than the current one,
in theory, yes.
but will the price continue down when it rises?
well , it depend how market going on , it all depends on the market player.
What is the probability of a bitcoin collapse?
i have no idea.
It is extremely likely that someone will attempt to take advantage of people's ignorance of the true nature of bitcoin.
the true nature of bitcoin as far i know is a electronic cash system,with peer to peer transaction system.
now u look like paranoid asking question like this.
