Trading can devolve into gambling, and sure there are likely more conservative trading methods that might not really be gambling, so there are not exactly bright lines in regards to the various categories, of investing versus trading versus gambling but they might sort of be on a spectrum in which many of us might not agree upon the thresholds upon which one of the practices might fall into being the next one.
Trading becomes gambling when someone who trades does not have knowledge about it and keeps on losing money. That means he is gambling with his money, but some people confidently compare these two things together, and I think they are not the same. However, the practices that can lead trading to gambling is when a trader keeps losing money and refuses to find a way to sort his problem out because when you lose too much and you are not making money out trading, that is gambling.
Even with good knowledge, a trader can still lose money in trading. That is the reason trading is often considered similar to gambling. As long as a trader can't accurately predict what will happen in the market, but instead bases their actions on assumptions from research due to various factors, it clearly shows that it also involves gambling. Anything that someone doesn't know the outcome of is considered gambling because it relies on assumptions.
So, if someone can't consistently make money through trading and will also encounter losses on some days, I don't think it would be better than investing. There is a probability that the losses a trader may encounter on any given day could be greater than the profits they make on other days. Some traders have made good money in trading before, but where are they now? They have lost all that money in trading again.for me, trading and gambling are likely the same because of the high risk involved.
