Whaleshares does has it's own wallet app. The current registration process requires a Bitshares account since that is how the original sharedrop claim process worked, it allows for user integration with our cross-chain whaletokens (the original idea behind SMTs), it is our gateway out to other crypto and fiat, and it allows us to verify user accounts easier. "creating synergy"

Plus we don't want 50,000 sock-puppet accounts from Steemit ruining the experience ;-)
