Hi, basic comparative questions that I think will intrigue a broader audience:

Nexus developer team always emphasizes that Nexus [NIRO] can peacefully co-exist with bitcoin.  Is there any structural reason, however, that bitcoin could not be phased out by market forces for NIRO in the coming years?


Is there anything unique about bitcoin, or any other altcoin, that Nexus [NIRO] cannot outperform?
 

What are the likely/plausible scenarios of losing essential functionality that will cripple Bitcoin and others in the upcoming
years that NIRO will survive?


What characteristics about NIRO cannot be copied retroactively to Bitcoin and other long standing altcoins?


Please answer in novice terminology so that answers are effectively tweetable.  Thank you.
