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's what trading wants from you, some time and a little concentration and if you do that you will be able to get all the things about it if what is going on in the markets and which coins are best for buying and when to sell them back.
