No specific way to earn BTC fast, you just need to search for a way, some are good at social factors and do good as affilates and promoters and that's relatively profitable although I haven't tried it, maybe that is what you are looking for?
The specific way is being a hardworker, passion in that method and really a desire to earn and accumulate more coins. If one has many methods but not much working on it then it's useless.
