If you use your entire money to invest in Bitcoin, then which money are you going to use for your personal upkeep? Does that mean anytime you need money, you should sell the Bitcoin you have stocked in your wallet? NO. That is why the advice to invest your spare money in Bitcoin is always good for new investors, so that they can buy Bitcoin with the aim of holding it for a long time.
You have missed the point. Not investing with your spare money does not mean you should invest all you have. What I mean, anyone still investing in bitcoin today with a spare money is a very big
joke. You can budget your and be fine in bitcoin investment.
For instance, if you earn $1000 monthly, after removing your living expenses and emergency fund, you can decide to invest 5 to 10% in bitcoin. This is not a spare money and it is not also a living expense money and neither is it an emergency fund.
When you say spare money, $3 can be the spare money of someone that earns $1000.
You do have a point and I bet others also understand your point. But I still think that it's still applicable. Maybe not for everyone, but for others, especially newbies. Those three advices you've mentioned are usually being advice to beginners since they are still exploring and starting their Bitcoin journey so it's not a bad thing to follow these advices. But of course, through time and if you learned enough, your ways of investing and thinking may change. Your level of risk may change and you may start investing more on Bitcoin and not just using your extra money. And same goes for the other advices. These advices may not be applicable to you anymore since you've had enough experience and knowledge, but these things can still be useful for others.
You have a point mate. This could be the advice given to newbies to keep them at their toes until they understand the system. But for someone who is well experienced, the advice is faulty.
