This is way too much imo
$50 for each ADA would result almost $1.5 Trillion marketcap (Not saying it is not possible but judge on how the market trend now)
It is kinda impossible
ADA is good as it has better way of scaling, infrastructure and bla bla
But, Blockchain is an emerging technology and it can be replaced real fast if they stop improving
If ADA could outperform most of the crypto and shine all the way, Yes
But as long as there's question like "Should i buy Ethereum, ADA, or EOS"?
Then no, when you have competitors, you can't really move upwards that much
