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.
Bitcoin become currency because bitcoin is now available for any transaction.Its a good currency especially when the price is increase.lt will give us more comfortable for any payments.
There are some place where bitcoin is accepted as a payment option but it does not reach wide enough yet.
I saw steam was accepting bitcoin before and i think it could be a very big opportunity for bitcoin but now its not accepted anymore. Does anyone know why? That is a very unfortunate thing.
