if I personally at this time I do not say an addiction. because they see bitcoin as a future opportunity and have the right steps to invest. so in this case I'm not saying it's an addiction like the op said. because addiction to bitcoin means that you invest in bitcoin as a hobby and you don't have the right direction.
Investing and being addicted are two different things.
I've seen a lot of crypto traders who are seriously addicted to trading, all they have to do is trade online and speculate on trading,
They do not hesitate to mortgage their houses and cars to invest in the market and expand their portfolio.
