I have seen a lot of rumors out there they are saying next bitcoin is a Litecoin it possible?
no, bitcoin will forever be on the top. If litecoin is the silver then the bitcoin is the gold. The total market value of Litecoin is currently lower: $18 billion to Bitcoins $291 billion.
I can not say so much. because I know for Ethereum that became an advantage and became the famous coin as the next coin for Bitcoin. other than that for Litecoin itself I have not seen its development that has improved so ensuring. therefore I am not sure to say that Litecoin becomes the next coin for Bitcoin.
