Because btc is the strongest crypto currency in d market while others follow..
It's the most valuable right now

Since bitcoins are the first of all, Altcoins is now connected to it all. So when the bitcoins fall we expect it to follow the altcoins. So this is my opinion why it means no # 1 to me. Notice that bitcoins have fallen, followed by altcoins.

Well the large fluctuations make it harder to use bitcoin as a currency , because when you buy something a week later you could have paid the double amount in dollar.

Bitcoin is still considered as a currency because it is a cryptocurrency or a digital currency which means it has a feature that is the same as a regular currencies like for example bitcoin can be used to buy stuffs online , yet i agree that large fluctiations make him a little harder to work as a currency because we can be able to pay double for the price tag if ever the value fluctuates but we can also pay lesser if ever the price of btc had decrease. Therfor it is still dependent.

Bitcoins properties and advantages are very useful to the modern era people because it is the first crypto currency  and later only its alternative coins are arrived in the market. Bitcoin has achieved the popularity among the crypto currency. More people are attracted to bitcoin  for the business transactions ,day trading and  investments etc.Bitcoin and the other currencies were first aware by the young computer and software technocrats. Finally bitcoins popularity has widen world wide and the people.from bitcoin loving countries are using it for their daily basic requirements as well as for the international shopping .Bitcoins market capital is very high and its market is volatile .It has a strong base and it is the number one in the market by all means.

This is quite true because these are the pointers and characteristics to which bitcoin is most known for. Without the creation of bitcoin, there would be a great nich in the investment world that could never be replaced by any other product or program. That is how amazing and beneficial to the mankind bitcoin is. That it would be a very big waste of potential if it gets down.

Of course bitcoin has all chances to become No. 1, but it will happen at least in 3-5 years. The authorities of the States find it difficult to recognize cryptocurrencies, as they do not know how to get more benefit from it. Unfortunately, in most countries, incompetent persons were in charge.

Bitcoin is the king first cryptocurrency that give high profit to all his investors. That give job to all jobless and help the world to reduce poverty and help the economy of every nation. Bitcoin is number 1 because of that reason.

For me when someone saying that bitcoin is number one , i think Bitcoin is more useful than other websites and bitcoin is number one for them and also for me bitcoin is the one who help people in life eho are indeed , and bitcoin make internet more useful.
