Bitcoin is not backed by any physical asset like Gold nor by any fiat currency. It makes me wonder if I should invest/trade in Bitcoin or not?
It is all about trust, because one cannot make a person feel it's value. Value of bitcoin in decimals during its existence. Later it started to grow gradually and has now marked a big change in value. This is all because of the increasing demand. If it hasn't got any real value the demand could've diminished with time rather than growing. So, real value of bitcoin can be felt by the one who believe in it.
