I am new to bitcoin but I was just saying that I will not take a whole ten years from this year that I started to have a significant amount of bitcoin, only to sell to buy a car, that buying a car shouldn't be why I got into bitcoin investment.

For you to be able to have a better knowledge on bitcoin investment, you must have the experience, and how do you have the experience by investing now, because you can simply invest and learn along the line, it is better to get started than to think that you need a major knowledge of bitcoin investment before you can invest. To invest in bitcoin it doesn't need much just only the basics of bitcoin which is how to buy and send to your noncustodial wallet. If it is someone that is use to save some little part of his income  always, the better for him. Bitcoin investment should be for a long term and this is why you should only use a percentage from your income that will not affect your other necessary expenses, you should also have  emergency funds that will be a back up for you when an emergency arise, so that you will be comfortable with your regular DCA to achieve your bitcoin goal. Success can be achieved, when you are discipline and patient in your accumulation period to make sure you don't get distracted along the line. Some people have been holding some good significant of bitcoin that they accumulated bit by bit for like 10yrs now.

DCA approach is very reliable for you to use as a newbie in your bitcoin goal. But if my any means, you can have extra funds from you place of work or your business, you can save it for the dip so that when the dip comes your are ready to take advantage of it. People that have good financial management with maybe a good source of income can easily use these methods with time. JJG has already stated this above because he is well experience on this field, since he started his bitcoin investment long ago and now he is on his maintenance level.
