Yup it is and a bigger exchange would be good exposure but only if the RaiBlocks project is making changes and has something to offer. Right now as it stands I don't see the reason why Bittrex should accept although I agree there is potential here. Because for one thing if there are zero fees for transactions (which I like btw) how does Bittrex or a big exchange get a piece? Are they going to take 0.5-2% in fees when withdrawing or what how does this part work I don't exactly know.
Bittrex will do whatever they want if the way they handle business is any indication. They'll have no issues taking fees on a no fee coin. They have no issues taking money from people considering the recent issues with so many people have their accounts essentially banned or frozen without any prior notice. Personally I hope XRB gets added to any other major exchange, Trex is scum.
Anyone unfamilair with current events can go read up on their main thread.
