If you trade shit coins, you will see yourself losing because they are too volatile. If you gain, you may later lose. Successful traders trade with less than 10 times of their trading funds. If you have $1000 for trading, using $100 makes you understand what trading is. If you use leverage, you are increasing the chance of you losing. Patient traders are more likely to earn.
I agree with what you said, trading shit coins will only make you lose, i have experienced it myself, it is true that it gives a big profit in the short term, but it doesn't take long for sure you will experience a bigger loss, preferring to trade in Bitcoin even though it gives long-term profits at least it is safer.
