I'm of the opinion that $HIVE should be on several big exchanges with several trading pairs just for the sake of exposure and ease of onboarding. At least in this early stage of HIVE adoption. Someone who has a Coinbase account and happened to listen to Crimsonclad's speech at Rare Evo might decide to pick up some $HIVE to see what this is all about.
We do need to develop decentralized options as well, so that we don't depend on CEXs down the line.
Early years --> a few big CEXs with lots of trading pairs
Teen years --> Many liquidity pools and DeFi options
It's defo preferable IMO too but no great loss here as I guess Bittrex is quite small!
