I don't think trading can be considered as gambling though both posses risks and both are unpredictable. However, trading for me is better than gambling since it requires discipline and analysis and if you treat trading as business you'll likely success
Before treating it has a business you need to learn first how trading works otherwise you can lose a lot of money in it. It is not so easy to make a profit from trading like how we think because timing is very important to buy and sell. Many experts also lost a lot of money in it so you should be very careful and don't just invest all your money in one or two coins. Need to diversify properly to reduce riks.
We all have a chance to learn trading, we will all start from the beginning and every stage has different approach and one thing that is necessary
is that you need to start with a small amount of money when you are just starting as eventually you will improve that will be the time that you will be more aggressive.
