You consider something else. The word bitcoin is progressively substituted with blockchain.
Nodes: btc is not the coin with the greater number of nodes anymore.
Volume: btc is still the n.1, but if it continues this way, it will not last.
Total cap: in a few months I am not sure btc will still be the n.1.
In conclusion, bitcoin will exist for a while, but I am not sure it will be the leading star.
Ixcoin depends on bitcoin, an advantage as long as btc stays strong.
Unless bitcoin innovates itself, new coins will fill the void generated by lack of constant innovation the financial system is asking. Bitcoin has still time to avoid the loss of its crown, all will be clear in a few months.
