For me personally, addiction is caused because it has become a necessity that must be done whether he is a gambler or an investment, a person who is addicted, so he doesn't care about the risks he faces, is he ready or not, he will do that.
In my opinion, the factors that influence a person's addiction to crypto or not are because he has experienced getting big profits and now he is in a difficult condition so he loses money, when he loses, he imagines the big profits he has earned so he looks like an addiction.
Addiction is actually bad things for everywhere be it gambling or any drugs or in trading . I have seen many peoples around me that those doesn't know properly about trading and even they don't study any analysis for investment so without any technical or fundamental analysis they do trading only depends on some pumps and rising so at the end of the day they face losses. And they invest extra money again to avoid this loss and in this case too they suffer from the same situation, many times I have heard from their mouths that it has become like an addiction to them. So I think doing trading or addicted to trade like this is one kind of gambling which can never bring profit.
