Bitcoin is so popular because it is the first decentralized cryptocurrency and the first cryptocurrency to be successfully acknowledged globally.  Aside from that, many cryptocurrencies were forked from Bitcoin.  Although Bitcoin is the most popular cryptocurrency, I disagree that it is the only popular one.  There are also other cryptocurrency that are popular and known globally such as ETH, USDT etc...


Man-made stuff are inventions... and Bitcoin is man-made.  I believe there is no need to confuse the reader. I think this is a clear identification of what an invention and what a discovery is:


And according to the definition, Bitcoin is clearly invented. 


Bitcoin will not save anyone from being poor.  It can make one richer if they have the money to invest in Bitcoin but if they have none or little amount of money to invest, they cannot become a millionaire or get rich, they can get profit ,yes, but not to the extent of changing their lives.



Developer and miner has the power to alter the network.  If they want, they can create a new fork of Bitcoin with different features and become the longest chain.  So it is not an absolute truth that no one can control Bitcoin, IMO.
