It is not so difficult. Bitcoin became the first cryptocurrency and a symbol of a new previously unknown market, it is the single currency, all originally equal to it. After the emergence of the altcoins the price is started to be measured in satoshis, BTC. A cryptocurrency you can only buy with Bitcoin. Now appeared such giants, as, for example, Ethereum and many altcoins are based on his base. But in order to remove the king from his throne, you need to significantly surpass it in many parameters, such as the number of transactions per second, their speed, price, anonymity, scalability and accessibility. If there is such a cryptocurrency that can be easily bought, converted into any other cryptocurrency/currency and it will correspond to the parameters listed above, then it will have all chances to become a new king. This is my vision on this issue.
