just my 2 bts here, and sorry if this sounds like a really dumb idea.. fiats are about to go the way of the dodo in the next couple years. people will flee them, even if it says bitGBP or something like that. offering bitGBP wont recruit new bts people imo.
what might recruit better is converting open minded dpos people in the altcoin space. bitPPC or bitNMC, something like that. something that shows that the rest of the crypto community finally sees the value in dpos and starts using the bts platform for their dac, delegates, their own bitasset, etc. create of flood of developers using the dpos framework, the api, the wiki articles that could be syndicated into their wallets help screens, you name it. dpos is the future, no doubt about that anymore.
