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.
