As humans, do we have to be addicted to brushing our teeth in the morning, or we should do it because of its importance?.
I am not sure if investing in Crypto (or maybe every project) is an addiction. It's just someone's way of trying not to miss every given opportunity, which is also a risk though. I personally, I invest to some extent, but I can't really say that I'm addicted to it.
I barely go for new projects because I'm not certain of it's outcome. But if it were to be airdrops, then count me in. But that still doesn't make it an addiction. Every opportunity seems too precious in the crypto space, since most projects don't give a 100% success guarantee at first.
