I think that the most common way to value Bitcoin is like valuing other currency by another currency.
Seeing to it that we all know all the factors that causes or affects supply and demand equilibrium.
Also the time we hold bitcoins. Time is very important factor.
I value bitcoin so much. Bitcoin is such a blessing because it blesses everyone. It also did help each and every investors across the globe in their finances. It also gives benefit to trade across the globe to earn profit. And bitcoin, I can say that it is a savior because it saves people from being poor and being so needy.
