Don't quit, its part of your growth. At thr first, many hindrances would came into our life but the last you will be successful person.
Negative thoughts will make you weak, the result is like that what you said, you will quit or stop but the positive will make even you had lose already a money, the result you will be a successful person.
So put into your mind the positive thought thoughts with wise personality and actions.
I like what you said, and its the fact that losing or frustrations are part of growing. Since we are into bitcoin / trading industry, losing is essential and if you can't accept the fact of losing then this is not for you. But if you will not give up and you manage to stand again then for sure success is going to be with you, just don't give up.
But its very clear that after two years of trying thing did not work out for the OP, he lost money and now its moving on precisely because trading is not for him. This is not a matter of will but of economic common sense.
