However, while investing in Bitcoin must be experienced, you can't invest at any point in time. But if you have experience with Bitcoin then you can definitely invest by following DCA method and accumulate it for a long time and sell it again.
I think a beginner should know the basic knowledge about bitcoin investment and grow his investment portfolio by buying bitcoins regularly using DCA method. Even if many people have no initial investment experience, by using DCA to buy Bitcoins on a weekly or monthly basis, they will gradually increase their investment experience as well as their investment.
A beginner don't need any basic knowledge about Bitcoin but can buy Bitcoin and learn more after they must have made investment already because waiting to acquire more knowledge about Bitcoin before investing may lead to loss of interest because you will always feel that the knowledge you have gotten is not enough to guide you all through your investment period and no one can know everything about Bitcoin so it's better to invest before getting the fundamental knowledge about Bitcoin. The DCA strategy is already a popular method by which every one has the opportunity to buy Bitcoin so they can decide when will be good enough to DCA either weekly or monthly
I think basic knowledge is very important for a beginner because, without it, some may not even know the right source to buy Bitcoin from. Some, after buying, don't know what the next step is, and because of this, their Bitcoin can be easily stolen from them. In fact, many can even lose money in the process of trying to purchase Bitcoin. So, with that, I would say it is a good idea for beginners to have some knowledge so it doesn't get too complicated when they are trying to invest in Bitcoin. I think losing money the first time they buy Bitcoin can also be discouraging for them. I know it will surely take time if beginners want to learn most of the necessary knowledge before investing in Bitcoin,but knowing how Bitcoin works like understanding that Bitcoin is a volatile asset and learning about scammers can save them from losing their funds.and know again it because of basic knowledge some beginners lack that make them even trying to attack even the person that introduced Bitcoin to them.
