I do not think so. It will never go back to bottom line again as it was in 2015. Since many people now are into this forum earning btc, there would be a little chance that its price would fall. We who will be making its value fly higher and should never give it back. It always depends on us on how we will handle it. There is not chance for not using btc. The strength has increased a lot. The price again started increasing. Very less chance for it.
and also this is not at all the same increase from 2013, i mean the price was not rushed all the way to 1200 in two week, we are increasing slowly, so i highly doubt that we can see a dump to $200 again, this current value is rock solid, i can say this because the recent hacker and bad news made it even more solid
I agree that bitcoin price is not rushed or a sudden bubble like it was in 2013. In addition to that there is more people behind bitcoin and several big companies are supporting it too. So i also don't think that bitcoin will collapse till it is worthless. Reason, development, promotion, adoption of this currency is still very active.
