Had Satoshi named it differently, Bitcoin would probably still be enjoying the success it has today, provided it won't be given too nuisance a name as BoobCoin or BeiberCoin. Bitcoin got its success from its features.
I don't think it would enjoy the sam success if it were named differently, even if it's not annoying sounding name. Probably we can get by with it given that it only takes acclimation to the names since it delivers what it does anyway.
