Maybe buying an iPhone will give that person temporary happiness but when a person spends that amount of money on investment without buying an iPhone, but in the future he will get a good amount of profit from this investment and it will be seen that he can buy more iPhones from the profit of that investment. But our brains think very little like this, we prioritize what we get in the short term or what happiness we get for the short term as opposed to spending money.
The priorities of the individual thinking about buying the iPhone matters because you do not know if that iPhone will be used for his business and bring more exposure to the business. A content creator needs that new technology more than anything elses because even if he buys the Bitcoin and does not have any other business for suitability, he will end up selling that Bitcoin to feed. Our business comes first before any other thing but your message has alot of sense in it for people that are buying the iPhone for pleasure when they do no need a new phone for anything serious. But also they should not just buy Bitcoin because we say so but buy only when they understand what Bitcoin is and what they are doing by becoming an investors.
