The common advice in the crypto space is to get knowledge before investing. That it is important to understand it as a whole before investing in Bitcoin. In reality, this is not what happens or how it plays out. How it works is that we heard about Bitcoin, invested first, and asked questions later. However, at what point should we say that we have had proper knowledge and understanding to go ahead and invest in Bitcoin. I think that it is when the individual feels that they are ready and I am also not against those who invest first and ask questions later. They'll learn the security , decentralization, and others on the "job".
Actually questions never ends and if you think that you have completely covered all the questions and now there is no need to ask anything then you are wrong. There are experts who also ask something because one cannot get whole knowledge at once as new thing arises which a person has to understand.
A person should invest through proper knowledge and whenever his mind feel something new then he can ask because there is no boundary of knowledge. Now it is important that you will get the important knowledge about crypto, its Characteristics, volatility and strategies prior to investment then learn more knowledge when you do investment.
