Thank you for sharing this. I believe majority of us especially the upcoming ones have no idea about this. Reading through the link shared, I discovered that eCash was actually the first cryptocurrency to be developed but it never achieved the level of success that Bitcoin has because eCash was not decentralized and this made it less appealing to those who were interested in the decentralization and transparency that Bitcoin offered.
Bitcoin is the king of all cryptocurrencies it goes without saying because other coins are dependent on Bitcoin but Bitcoin is not dependent on any coin. Other coins are dependent on a third party but Bitcoin is a currency that has no ownership of its own or ownership that has not yet been disclosed. So it has monopolized the highest position in the market.
Bitcoin has the longest track record of any cryptocurrency and it's the most widely known and used, this alone makes it to be the king of all cryptocurrencies. The fact that Bitcoin is the most decentralized cryptocurrency meaning that it's not controlled by any one person or group because other cryptocurrencies are often developed by companies or individuals but Bitcoin is truly decentralized and this is why majority adopt it.
