Cryptocurrency is very addictive especially when you encounter its higher value. But still its better to not be addictive in anything because sometimes it cause harm to someone, its better if we have control to ourselves so that we can avoid being addictive. Even being addictive in earning in crypto is good but we should be balance especially when we do investing just to get profit.
