We don't really need a separate crypto for booking movie tickets and another one to book flight tickets! All can be done through one crypto.
Glad you said it because I would have if you hadn't. That's one of the reasons why I won't invest in ico projects, because they all are trying to tokenize solutions to problems where it just doesn't make any sense, and the same thing is true for most new altcoins. A lot of them try to be 'specialty' coins to be used in certain industries, but there's no need for that. Remember RBIES? Reddcoin? Sexcoin? All of them are unnecessary for what their stated purposes are.
Ripple's ceo is probably right, because 99% of coins on the market right now serve no real purpose and most of them don't have significant communities supporting them. A lot of them are even dead already, with no blocks being mined and no trading going on. That's where most of them are headed in my opinion.
