Trading is a big work on yourself. Here the main role is played by the availability and analysis of the situation, in contrast to gambling, where everything is decided by chance.
I think there is no comparison between trading and gambling because trading is a business and gambling is the worst thing in the world. There is no future of gamblers but the future of a good and successful trader is very bright. Therefore I think that bitcoin trading is far better than bitcoin gambling. Both are opposite of each other and consist of many differences.
You are right, if we choose gambling then there will only be one - three people who will succeed, but if we trade then there will be many successful people
