There is no first move advantage.
If anything it's a disadvantage.
Look at all the people who won't get into Bitcoin because it's "too expensive" or "low tech".
Look at Myspace and Netscape; did they have a first move advantage? Nah. Crushed.
ADA and BNB can't even be on that list because they aren't mined.
BNB is more of a stock 2.0 coin... well at least before the EVM network came into play.
LTC is a decent example though.
It's a great example of how people do not respect POW technology or understand the value or usecase.
They'd rather jump into some new thing that promises the world and never delivers.
