In the beginning, BTC could be used to exchange of low value of virtual items, such as buying web sites or game points, virtual items, etc., afterwards, some people in order to get these virtual items, items may be in online auction own reality for BTC, others want to buy the real goods, but no BTC at hand, and then use real money to exchange BTC, as a result, BTC begin to flow, and have a "value".
In other words, bitcoin is inherently valuable as a means of payment; If it loses its function as a means of payment, it becomes worthless.
The value of money: it exists because of payment.
It is indeed exist because it is used for transactions online like betting sites. Now it is also used as the basis for exchanging in different coins that emerged in the market. The value of Bitcoin exist through the continues patronage of people to it's usage.
I think the government must approve it, if the government does not agree with bitcoin and crypto then how can bitcoin become a world currency. and don't spread hoaxes that aren't right about bitcoin.
