The inventor of the most famous cryptocurrency today – Bitcoin – attempted to build a “peer-to-peer electronic cash system”. This had been tried many times before but the main point of difference between Bitcoin and previous efforts like Digicash was that it was to be entirely decentralised. Without an overarching entity controlling the currency, the notion of “trust” would be removed from the system.

To combat “double spending”, the major flaw in all digital cash systems at that point, Bitcoin inventor Satoshi Nakamoto proposed a revolutionary technology known as the blockchain to record all the transactions made with his currency.

For any single balance, transaction, or change to the network to take place, there would need to be consensus amongst those validating the network – the miners. Since Bitcoin’s invent, many other programmers have attempted to use the model and tweak it to provide what they consider to be a more functional form of digital cash.

Other cryptocurrencies include Litecoin, Monero, Ether, and New Economy Movement. Many of these efforts tailor their currency for a special purpose. Speed, price, and privacy, are among the most common.

Bitcoin is the original crypto-currency. That is why it is so popular. Other altcoins are mostly copycats, who depend on manipulation and pumps to move up their exchange rates. But Bitcoin has grown to such an extent that even manipulation of the exchange rates is so hard to perform.

why you know bitcoin?  Bitcoin is popular because of its price.. people who are not familiar with the crypto currencies when heard about the bitcoin they are first shocked to hear the price of bitcoin.. so definitly price is one of the factor that makes the bitcoin popular.

Bitcoin is the most popular crypto currency as it the first crypto currency ever created in the crypto market rest all other crypto currencies are just a mere copy or a clone of bitcoin and blockchain technology.  Bitcoins are created by through mining like Gold by solving complex arithmetical equations which helps to earn bitcoins and every time the level of difficulty of mining increases as there is only a limited number of bitcoins available in the crypto market. The value of bitcoins increases every year due to high demand of bitcoins which attracts more user's to the blockchain technology.

For me bitcoin is the most popular cryptocurrency because of its high value if you exchange it into fiat money.

First thing is always attractive and worthy, the father of all crypto is bitcoins , i think this is the only reason behind this, the old and most trusted crypto.

Besides of being the first crypto in this world. Bitcoin is decentralized. No one owns or controls Bitcoin that is why people is attracted on using Bitcoin. People wants privacy and this coin is the first answer to our wish.

Because Bitcoin was the first crypto currency so it is more popular in world.  it was made before any other crypto had been developed.  Definitely Bitcoin price is one of the factor that makes popular currency.

Because contrary to popular belief, altcoins with faster and cheaper transactions do not have better tech than bitcoin does. They either have too low volume to have scaling problems, completely centralized or just have bigger blocks (which is a retarded solution to scaling problem). Bitcoin has its own problems but is the most reliable coin we have.

There are many reasons to become bitcoin more popular. As bitcoin is digital, so there is no scope to be fraud. That's why it so popular now.
