Obviously other currencies have been aiming to tackle the scalability issues that Bitcoin is being presented with.
Obviously if the Lightning Network is not successfully implemented, the likes of coins like XRP will fill in the gap that banks need for fast cheap liquidity.
Will the lightning network be game over for the rest of the ALT coins that are borderline built on scalability?
Let me know what you guys think.
For scalability- yes the LN would apparently solve the issue. But you need to understand that LN is a sidechain. It collects the payments in bulk and broadcast into the bitcoin network at one go. So LN is a temporary solution for now. Even though LN is live since last few months, it has not yet received enough attention that it deserves.
Secondly people are already using altcoins for their daily transactions because they are fast and cheap. Why do you think BNB coin is constantly rising up? Bitcoin is mostly considered as an investment unfortunately so even LN would not be able to bring down the alts in any way!
