Unfortunately most of the traders are like you, they want to learn only after facing losses. If we are all learn first then trade then there would be any chances for disappointment in trading
You meant to say that there would not be any chances for disappointment?
I guess this is farther from truth that you may think. If we talk about Bitcoin, which is pretty much a zero sum game, someone will always be losing, and most likely it will be the majority of traders. If there really wouldn't be any any chances for disappointment, it would basically amount to no one losing their money, which is just impossible (someone should be left holding the bag). In this manner, it is a sure thing to assert that no matter how hard most traders might try to learn, they will still be losing on average
