Hence, dollar is product like food or clothing, with the capacity to be used, consumed or practically utilized by its end users - borrowers.
We cannot deny that the existence of the dollar and other cash currencies always gets a place in the community and can be accepted by the wider community. Understandably, the dollar is a currency that is fully supported by the government, no wonder its existence is considered to have a broad and practical capacity.
Bitcoin on the other hand has no such utilizable capacity - it cannot be used, which is why it can only be transferred - i.e. passed from address-to-address, from hand-to-hand, from member-to-member. In other words, in the bitcoin circulation chain, nobody is able use bitcoin, like in the case of dollars, goods, services and similar utilizable resources..., which is why such resources can be obtained from new investors only.
Because, the existence of bitcoin has been complicated by the government with various restrictions, so that bitcoin cannot function properly, like fiat currencies produced by the government. But, have you ever imagined, what would happen, if bitcoin were adopted massively?
