Yes, bitcoin is not supported by anyone. It would be very difficult to answer this question. Simply put, the value of bitcoin will continue to exist if it is still used by the community, if it is not used again directly its value will be lost. The logic goes like this, If you invest in bitcoin it means you are a supporter of bitcoin to keep its value. This means that the value of bitcoin depends on the person who uses it, and there applies the law of the market, namely "supply and demand".
I’ve been trading forex for quite a while now and the value of currencies depends on many factors other than demand and supply alone. Is there any other factor (except demand & supply of course) which impacts the value of bitcoin?
I think there is None? because market will only move(Specially in volatile market like this) because of Supply and Demand . same as in all trading platform it the world,
Yes this maybe a currency that can be use even not in trading but back up is from US who Use this and there is no need for physically back up.
Bitcoin and altcoins have value because they are used by the community and the number of active communities is very large, value occurs because of demand and stock as is the case with the market.
well the question is about back up and not the use of this coin.
I still think that there is no need for back up as long as people is using this and not for another way .
