Depends upon what you mean by sink into oblivioun. If you are referring to price, that might not be the case. BTC has the publicity and a lot of people will look to hold it. There is a scarcity to it which could give it the market cap of gold.
That said, as a network, it is not going to be much of a player. It will have still be used for large moves of value, since it has liquidity and is a secure network. However, outside of that, it is not really offering much that I can see.
