I don't see what the moaning is all about, you never expected all this methods of earning bitcoin to be "easy", did you?.
And it depends on what actually you mean when you say it's difficult, imho it's just dedication and effort, not difficulty per se, to make money or profits is never easy, I enjoy trading, I also hodl a part of my coins.if you find it too difficult to earn through this means you listed, then I suggest you buy bitcoins with your local fiat currency.
I always woke up having 20 posts deleted almost everyday and all the comments ive posted removed because of off-topic reasons. I always end up not having a minimimum post count on my campaign...
Then it's left for you to work on yourself and your posts, make them more constructive and relevant to the ongoing discussion, that way it'll reduce the amount of posts you get deleted, though it's impossible not to have posts deleted, but on a fewer rate.
Do not also see signature campaigns as a job, if you cannot reach the maximum posts, it's nothing to be upset about, and it's actually better than spamming the forum just to make sure you do.
