I don't know why some folks are still thinking that you must have all the knowledge before he/she could start investing in Bitcoin, it is a totally ideas because Bitcoin is so wild in such that you can't finish all knowledge when it comes to Bitcoin, once you are still thinking that you not ready to buy Bitcoin and your discretionary income is available for you which you could have use to invest, what i will advise to those folks that think is not good to invest now that they will wait till when they have full knowledge and which i know that they can't finish knowing all Bitcoin finish because Bitcoin is something that keeps updating every single day, so those folks not to regret letter run, so it is better to buy now as you can afford using DCA strategy which can motivate you of not losing all you have invested for.
I quite agree with some of the things you said here, but the angle were I have little disagreement with you is were I highlighted in your post. I'm having troubles trying to figure out what you mean by "bitcoin keeps updating every single day" What updating are referring to please? Does it mean that the knowledge that were applicable in bitcoin investment few years ago are no longer valid or applicable today?
But to the best of my understanding, same application of those knowledge that worked for early investors are still working for those that came into bitcoin investment 1, 2, 3 years ago, even those that came yesterday and will still work for those that will come onboard in the future. It's just like mathematical formula, all you need do is follow the right formula and you will get the desired result. The buying methods has remained the same over the years, the total supply has been the same and will forever remain at 21 million. So I wonder what's actually updating every single day according to what you said above.
