Can the price drop very low to a dollar?
Will it go very, very high???
Tell us what's possible and what's not, and what you expect please.
Nobody know this for sure mate. Bitcoin is still just an experiment that still even in beta. As each day passes, Bitcoin is stronger and eventuality that its price will drop to zero is lower and lower. But anything can happen.
Be careful how much you are investing. Invest what you can afford to lose and enjoy the ride, and the finish will be very positive, we all hope so.
Yes investing all your wealth is not at all recommend by many veterans of bitcoin as it's still a experiential project even evolving over time. Invest little and spread word on bitcoin to make people aware of bitcoin and it's opportunity. This will be making you in a winning situations.
