i firmly believe in that belief. if you want to start trading then your emotions should be as strong and sturdy as diamond. Crypto can be very vicious and can suck the last droplet of happiness in your system and make you less appreciative of money earned--always wanting more. a dip can case you to purge and literally lose yourself in regret. That is why you will come to think of the phrase "invest what you can afford to lose" this is not created just to limit what you invest but this is to keep your sanity. Trade at your own risk, do not be consumed by emotions and learn to move forward from a mistake and learn what you need to learn.
