Some people have given different testimonies of their earnings so far and you some times ask yourself, "Will it be possible for me to earn that much?"
You might be facing some challenges now, such that the ICO you are promoting is taking a long time; you are not being paid early enough or not seeing your tokens list on exchange and sometimes falling victim of scam project. All these might make you think of quitting, like i have seen some done.
One thing i want you to know is that, this is one of the best times you should not quit, because some cheaters have been discouraged from cheating with multiple accounts and now find it hard to cheat.
Aside every other things too, an accumulated work done can bring about accumulated reward.
By the time you begin to reap the harvest of the works you have done, it might seem like a dream.
But still it depends on the market right away, even a project is good but the market is worse, still the project will going to have hard time implementing their road maps. Also investors are discouraged to invest on projects.
