And right now it's at $20.50, so I don't think there's a chance of bnb hitting $50 this year unless bitcoin has an amazing rally and bnb goes along for the ride.

I'm shocked that it's even in the $20 range, which is outstanding for an altcoin in a market where most of them trade for pennies.  I think a lot of that has to do with the popularity of Binance as an exchange, which of course is a reputation they've earned.  No doubt bnb *can* reach $50 and probably even more than that, but it's going to depend on if and when altcoins in general start to move upward and whether Binance retains its #1 position among exchanges. 

If anything happens that causes them to lose their popularity, I would expect that bnb would drop...and fast, too.
