For me the reality is Bitcoin cannot be a currency just for the fact that people using it are after the gains ,having profit as a top reason.
But i guess that is just for now ,Bitcoin will undergo phases to be accepted as a currency in the future.
Now Bitcoin is used primarily as a means of accumulating value, since in general it increases in value every year. To a large extent, this is why it is very poorly used as a means of payment. What happens if bitcoin stops growing in price? I often ask myself this question. In my opinion, if this happens, the demand for it will drop sharply, and therefore the price for it will fall. Will it ever be used consistently as a means of payment? There are also many questions and insoluble problems.
At the same time, cryptocurrency as a whole is rapidly developing and improving. Its circulation in the future together with the usual currency is already undeniable.
bitcoin has 21 million coins, and now only 3 million coins are not yet mined,
we know 2020 is halving bitcoin, and bitcoin will be difficult to mine,
but remember it's not just bitcoin in the world that is popular, ethereum, waves, xrp and tron is the future king of this crypto currency
