If you go by anyhow articles you found, and by YouTube/Social media posts, you would make a mistake. Find a reliable article source from true professionals, especially NGOs and the health-related field.
The first link I posted is about a rehabilitation centre that said at least 1% of crypto traders may be addicted to trading. The second link on the second post is about something similar. I know how lies can be online but I do not consider this one as one. From how trading is, I also think it can be addictive as a result of dopamine effect. Just as people make money and lose money from gambling, the same dopamine effect can occur if it is trading.
But don't forget, it's not about trading being addictive (it is addictive), but which one is more addictive between trading and gambling.
The OP asked if trading can be addictive like gambling, he did not ask of which one is more addictive. Let me give more reasons that trading can be addictive.
What I saw about trading in the past is that out of many traders that are losing, some people among them will stop trading while some people among them will change to swing trading or holding, while few will still continue to gamble and probably lose. I can find out where I read about it and it was a research. Although, I did not read the methodology used for the research.
95% of gamblers are estimated to be losing, while 85% of crypto traders are estimated to be losing. But people will continue to trade which I think will cause the addiction because high percentage of people are losing while trading. The addicts could be less in number if compared to gambling but I think there are people that will one way or the other be addicted to trading. Of 85% of them are losing, info not think many traders should be trading by now but many people continue to trade.
