Feeling the stress would mean you really take seriously trading, I am still starting to trade and I am not in profit yet, I started with a little amount to experiment if I have the skills to make money in trading but seems it is not that easy so I need to adjust my method from time to time until I hit it right.
That is the process of building trading experience.
Just continue to your own strategy to make up some nice trading strategy hence it will take you for a trading success.
And that success will give you more saved bitcoins continously.
