Obsession is different from necessity. Ofcourse everyone has the drive to earn money but it would be another story if we would talk about obsession. Obsession means you'd do something no matter what circumstances you would face or encounter. On the other hand, it won't also be a good thing to be obsessed with Bitcoin. It is okay to have investments into it but diversification will still be more advisable. Bitcoin indeed has a higher market price volatility but that won't guarantee big profit already 'coz in line with its volatility issues, are instances wherein the market price would fall. Gambling addiction indeed is different with Bitcoin investment but both has risk, so you decide where to engage yourself with.
You are right, there is a difference between obsession and necessity. Investing in Bitcoin can be an interesting choice, but it is important to consider diversification to mitigate the risks associated with its volatility. Addiction to gambling and investing carries risks, so consider your financial decisions carefully.
