I personally think bitcoin has a higher tendencity to stay on the market and won't go off. Bitcoin is the grandpapa of all cryptos and hence have the ability to stay on the market and pave way for other cryptos, hence bitcoin is no match to other cryptos. Every ground breaking projects attracts investors and promoters. Bitcoin as a ground breaking project will certainly be acceptable everywhere in the world. Since other countries wants to invent their own cryptos, there will certainly be fighters of bitcoin, nevertheless, bitcoin still remains the peak. Bitcoin has already started proving people wrong. People never believed it will last for even a year when it came in 2009, but we are in 2018 and bitcoin is still popping higher. As the internet literacy rate in countries increases, and people gets to know more about internet trading and marketting, bitcoin will raise the economic status since there will be a lot of bitcoin millionaires in the system.
Not to destroy your very very positive views and beliefs into Bitcoin. I would like to ask you this. Why you are so sure? remember that nothing do last forever into its spot. We cant really deny that bitcoin is really a revolutionary thing that had been discovered which do give us out a benefit when it comes to payment system and together it do gives a money making opportunity but it cant really guarantee a top spot forever which on all coins in the market theres always a tendency of switching places but this all depends on users support on which coin will able to have the better benefits.
